Swap around the GRE and VLAN parts in the flow-key offloaded by
the driver to fit in with other tunnel types and the firmware.
Without this change used cases with GRE+VLAN on the outer header
does not get offloaded as the flow-key mismatches what the
firmware expect.

03d5005ff7 nfp: avoid unnecessary check warnings in nfp_app_get_vf_config
nfp_net_sriov_check is added in nfp_app_get_vf_config which intends
to ensure ivi->vlan_proto and ivi->max_tx_rate/min_tx_rate can be
read from VF config table only when firmware supports corresponding
capability.

However, "nfp_app_get_vf_config" can be called by commands like
"ip a", "ip link set $DEV up" and "ip link set $DEV vf $NUM vlan
$param" (with VF). When using commands above, many warnings
"ndo_set_vf_<cap_x> not supported" would appear if firmware doesn't
support VF rate limit and 802.1ad VLAN assingment. If more VFs are
created, things could get worse.

Thus, this patch add an extra bool parameter for nfp_net_sriov_check
to enable/disable the cap check warning report. Unnecessary warnings
in nfp_app_get_vf_config can be avoided. Valid warnings in kinds of
vf setting function can be reserved.

842c3b3ddc mellanox: mlx5: avoid uninitialized variable warning with gcc-12
gcc-12 started warning about 'tracker' being used uninitialized:

  drivers/net/ethernet/mellanox/mlx5/core/lag/lag.c: In function ‘mlx5_do_bond’:
  drivers/net/ethernet/mellanox/mlx5/core/lag/lag.c:786:28: warning: ‘tracker’ is used uninitialized [-Wuninitialized]
    786 |         struct lag_tracker tracker;
        |                            ^~~~~~~

which seems to be because it doesn't track how the use (and
initialization) is bound by the 'do_bond' flag.

But admittedly that 'do_bond' usage is fairly complicated, and involves
passing it around as an argument to helper functions, so it's somewhat
understandable that gcc doesn't see how that all works.

This function could be rewritten to make the use of that tracker
variable more obviously safe, but for now I'm just adding the forced
initialization of it.

647df0d41b net: amd-xgbe: fix clang -Wformat warning
see warning:
| drivers/net/ethernet/amd/xgbe/xgbe-drv.c:2787:43: warning: format specifies
| type 'unsigned short' but the argument has type 'int' [-Wformat]
|        netdev_dbg(netdev, "Protocol: %#06hx\n", ntohs(eth->h_proto));
|                                      ~~~~~~     ^~~~~~~~~~~~~~~~~~~

Variadic functions (printf-like) undergo default argument promotion.
Documentation/core-api/printk-formats.rst specifically recommends
using the promoted-to-type's format flag.

Also, as per C11 6.3.1.1:
(https://www.open-std.org/jtc1/sc22/wg14/www/docs/n1548.pdf)
`If an int can represent all values of the original type ..., the
value is converted to an int; otherwise, it is converted to an
unsigned int. These are called the integer promotions.`

Since the argument is a u16 it will get promoted to an int and thus it is
most accurate to use the %x format specifier here. It should be noted that the
`#06` formatting sugar does not alter the promotion rules.

487994ff75 net: dsa: realtek: rtl8365mb: fix GMII caps for ports with internal PHY
Since commit a18e6521a7d9 ("net: phylink: handle NA interface mode in
phylink_fwnode_phy_connect()"), phylib defaults to GMII when no phy-mode
or phy-connection-type property is specified in a DSA port node of the
device tree. The same commit caused a regression in rtl8365mb whereby
phylink would fail to connect, because the driver did not advertise
support for GMII for ports with internal PHY.

It should be noted that the aforementioned regression is not because the
blamed commit was incorrect: on the contrary, the blamed commit is
correcting the previous behaviour whereby unspecified phy-mode would
cause the internal interface mode to be PHY_INTERFACE_MODE_NA. The
rtl8365mb driver only worked by accident before because it _did_
advertise support for PHY_INTERFACE_MODE_NA, despite NA being reserved
for internal use by phylink. With one mistake fixed, the other was
exposed.

Commit a5dba0f207e5 ("net: dsa: rtl8365mb: add GMII as user port mode")
then introduced implicit support for GMII mode on ports with internal
PHY to allow a PHY connection for device trees where the phy-mode is not
explicitly set to "internal". At this point everything was working OK
again.

Subsequently, commit 6ff6064605e9 ("net: dsa: realtek: convert to
phylink_generic_validate()") broke this behaviour again by discarding
the usage of rtl8365mb_phy_mode_supported() - where this GMII support
was indicated - while switching to the new .phylink_get_caps API.

With the new API, rtl8365mb_phy_mode_supported() is no longer needed.
Remove it altogether and add back the GMII capability - this time to
rtl8365mb_phylink_get_caps() - so that the above default behaviour works
for ports with internal PHY again.

47e96930d6 net: dsa: mv88e6xxx: use BMSR_ANEGCOMPLETE bit for filling an_complete
Commit ede359d8843a ("net: dsa: mv88e6xxx: Link in pcs_get_state() if AN
is bypassed") added the ability to link if AN was bypassed, and added
filling of state->an_complete field, but set it to true if AN was
enabled in BMCR, not when AN was reported complete in BMSR.

This was done because for some reason, when I wanted to use BMSR value
to infer an_complete, I was looking at BMSR_ANEGCAPABLE bit (which was
always 1), instead of BMSR_ANEGCOMPLETE bit.

Use BMSR_ANEGCOMPLETE for filling state->an_complete.

15ef9efa85 net/mlx5e: CT: Fix cleanup of CT before cleanup of TC ct rules
CT cleanup assumes that all tc rules were deleted first, and so
is free to delete the CT shared resources (e.g the dr_action
fwd_action which is shared for all tuples). But currently for
uplink, this is happens in reverse, causing the below trace.

CT cleanup is called from:
mlx5e_cleanup_rep_tx()->mlx5e_cleanup_uplink_rep_tx()->
mlx5e_rep_tc_cleanup()->mlx5e_tc_esw_cleanup()->
mlx5_tc_ct_clean()

Only afterwards, tc cleanup is called from:
mlx5e_cleanup_rep_tx()->mlx5e_tc_ht_cleanup()
which would have deleted all the tc ct rules, and so delete
all the offloaded tuples.

Fix this reversing the order of init and on cleanup, which
will result in tc cleanup then ct cleanup.

a6958951eb au1000_eth: stop using virt_to_bus()
The conversion to the dma-mapping API in linux-2.6.11 was incomplete
and left a virt_to_bus() call around. There have been a number of
fixes for DMA mapping API abuse in this driver, but this one always
slipped through.

Change it to just use the existing dma_addr_t pointer, and make it
use the correct types throughout the driver to make it easier to
understand the virtual vs dma address spaces.

35b42dce61 net: mdio: unexport __init-annotated mdio_bus_init()
EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.

modpost used to detect it, but it has been broken for a decade.

Recently, I fixed modpost so it started to warn it again, then this
showed up in linux-next builds.

There are two ways to fix it:

  - Remove __init
  - Remove EXPORT_SYMBOL

I chose the latter for this case because the only in-tree call-site,
drivers/net/phy/phy_device.c is never compiled as modular.
(CONFIG_PHYLIB is boolean)

7bb0fb7c63 ixgbe: fix unexpected VLAN Rx in promisc mode on VF
When the promiscuous mode is enabled on a VF, the IXGBE_VMOLR_VPE
bit (VLAN Promiscuous Enable) is set. This means that the VF will
receive packets whose VLAN is not the same than the VLAN of the VF.

For instance, in this situation:

┌────────┐    ┌────────┐    ┌────────┐
│        │    │        │    │        │
│        │    │        │    │        │
│     VF0├────┤VF1  VF2├────┤VF3     │
│        │    │        │    │        │
└────────┘    └────────┘    └────────┘
   VM1           VM2           VM3

vf 0:  vlan 1000
vf 1:  vlan 1000
vf 2:  vlan 1001
vf 3:  vlan 1001

If we tcpdump on VF3, we see all the packets, even those transmitted
on vlan 1000.

This behavior prevents to bridge VF1 and VF2 in VM2, because it will
create a loop: packets transmitted on VF1 will be received by VF2 and
vice-versa, and bridged again through the software bridge.

This patch remove the activation of VLAN Promiscuous when a VF enables
the promiscuous mode. However, the IXGBE_VMOLR_UPE bit (Unicast
Promiscuous) is kept, so that a VF receives all packets that has the
same VLAN, whatever the destination MAC address.

803e9895ea ixgbe: fix bcast packets Rx on VF after promisc removal
After a VF requested to remove the promiscuous flag on an interface, the
broadcast packets are not received anymore. This breaks some protocols
like ARP.

In ixgbe_update_vf_xcast_mode(), we should keep the IXGBE_VMOLR_BAM
bit (Broadcast Accept) on promiscuous removal.

This flag is already set by default in ixgbe_set_vmolr() on VF reset.

c76acfb7e1 net: phy: dp83867: retrigger SGMII AN when link change
There is a limitation in TI DP83867 PHY device where SGMII AN is only
triggered once after the device is booted up. Even after the PHY TPI is
down and up again, SGMII AN is not triggered and hence no new in-band
message from PHY to MAC side SGMII.

This could cause an issue during power up, when PHY is up prior to MAC.
At this condition, once MAC side SGMII is up, MAC side SGMII wouldn`t
receive new in-band message from TI PHY with correct link status, speed
and duplex info.

As suggested by TI, implemented a SW solution here to retrigger SGMII
Auto-Neg whenever there is a link change.

v2: Add Fixes tag in commit message.

54c2cc7919 USB / Thunderbolt changes for 5.19-rc1
Here is the "big" set of USB and Thunderbolt driver changes for
 5.18-rc1.  For the most part it's been a quiet development cycle for the
 USB core, but there are the usual "hot spots" of development activity.
 
 Included in here are:
 	- Thunderbolt driver updates:
 		- fixes for devices without displayport adapters
 		- lane bonding support and improvements
 		- other minor changes based on device testing
 	- dwc3 gadget driver changes.  It seems this driver will never
 	  be finished given that the IP core is showing up in zillions
 	  of new devices and each implementation decides to do something
 	  different with it...
 	- uvc gadget driver updates as more devices start to use and
 	  rely on this hardware as well
 	- usb_maxpacket() api changes to remove an unneeded and unused
 	  parameter.
 	- usb-serial driver device id updates and small cleanups
 	- typec cleanups and fixes based on device testing
 	- device tree updates for usb properties
 	- lots of other small fixes and driver updates.
 
 All of these have been in linux-next for weeks with no reported

4ad680f083 Staging driver updates for 5.19-rc1
Here is the big set of staging driver updates for 5.19-rc1.
 
 Lots of forward progress happened this development cycle, one driver
 (wfx wireless driver) got merged into the real portion of the kernel,
 and another one (unisys) was removed as no one is around anymore to take
 care of it and no one has the hardware.  Combined with loads of tiny
 driver cleanups overall we removed 13k lines of code from the tree, a
 nice improvement.
 
 Other than the wfx and unisys driver changes the major points of this
 merge is:
 	- r8188eu driver cleanups.  So many cleanups.  It's amazing just
 	  how many things have been cleaned up here, and yet, how many
 	  remain to go.  Lots of work happened here, and it doesn't look
 	  to slow down any time soon.
 	- other wifi driver cleanups.  Not as many as the r8188eu
 	  driver, but still pretty impressive from a janitorial point of
 	  view.
 	- bcm2853 driver cleanups
 	- other very minor driver cleanups
 
 All of these have been in the linux-next tree for weeks with no reported
 issues.
 
 Note, you will have a merge conflict in the
 drivers/net/wireless/silabs/wfx/sta.c file, please just take the change
 that came in from the wifi tree.  We thought as I had pulled the same
 merge point from the wifi developers this type of conflict wouldn't have
 happened, but for some reason git flags it as something to pay attention
 to and couldn't resolve it itself.

839612d23f net: stmmac: use dev_err_probe() for reporting mdio bus registration failure
I have a board where these two lines are always printed during boot:

   imx-dwmac 30bf0000.ethernet: Cannot register the MDIO bus
   imx-dwmac 30bf0000.ethernet: stmmac_dvr_probe: MDIO bus (id: 1) registration failed

It's perfectly fine, and the device is successfully (and silently, as
far as the console goes) probed later.

Use dev_err_probe() instead, which will demote these messages to debug
level (thus removing the alarming messages from the console) when the
error is -EPROBE_DEFER, and also has the advantage of including the
error code if/when it happens to be something other than -EPROBE_DEFER.

While here, add the missing \n to one of the format strings.

6e1ff61873 ice: fix access-beyond-end in the switch code
Global `-Warray-bounds` enablement revealed some problems, one of
which is the way we define and use AQC rules messages.
In fact, they have a shared header, followed by the actual message,
which can be of one of several different formats. So it is
straightforward enough to define that header as a separate struct
and then embed it into message structures as needed, but currently
all the formats reside in one union coupled with the header. Then,
the code allocates only the memory needed for a particular message
format, leaving the union potentially incomplete.
There are no actual reads or writes beyond the end of an allocated
chunk, but at the same time, the whole implementation is fragile and
backed by an equilibrium rather than strong type and memory checks.

Define the structures the other way around: one for the common
header and the rest for the actual formats with the header embedded.
There are no places where several union members would be used at the
same time anyway. This allows to use proper struct_size() and let
the compiler know what is going to be done.
Finally, unsilence `-Warray-bounds` back for ice_switch.c.

Other little things worth mentioning:
* &ice_sw_rule_vsi_list_query is not used anywhere, remove it. It's
  weird anyway to talk to hardware with purely kernel types
  (bitmaps);
* expand the ICE_SW_RULE_*_SIZE() macros to pass a structure
  variable name to struct_size() to let it do strict typechecking;
* rename ice_sw_rule_lkup_rx_tx::hdr to ::hdr_data to keep ::hdr
  for the header structure to have the same name for it constistenly
  everywhere;
* drop the duplicate of %ICE_SW_RULE_RX_TX_NO_HDR_SIZE residing in
  ice_switch.h.

c6fbbf1eae nfp: remove padding in nfp_nfdk_tx_desc
NFDK firmware supports 48-bit dma addressing and
parses 16 high bits of dma addresses.

In nfp_nfdk_tx_desc, dma related structure and tso
related structure are union. When "mss" be filled
with nonzero value due to enable tso, the memory used
by "padding" may be also filled. Then, firmware may
parse wrong dma addresses which causes TX watchdog
timeout problem.

This patch removes padding and unifies the dma_addr_hi
bits with the one in firmware. nfp_nfdk_tx_desc_set_dma_addr
is also added to match this change.

25bde571b4 sfc/siena: fix wrong tx channel offset with efx_separate_tx_channels
tx_channel_offset is calculated in efx_allocate_msix_channels, but it is
also calculated again in efx_set_channels because it was originally done
there, and when efx_allocate_msix_channels was introduced it was
forgotten to be removed from efx_set_channels.

Moreover, the old calculation is wrong when using
efx_separate_tx_channels because now we can have XDP channels after the
TX channels, so n_channels - n_tx_channels doesn't point to the first TX
channel.

Remove the old calculation from efx_set_channels, and add the
initialization of this variable if MSI or legacy interrupts are used,
next to the initialization of the rest of the related variables, where
it was missing.

This has been already done for sfc, do it also for sfc_siena.

183614bff5 sfc/siena: fix considering that all channels have TX queues
Normally, all channels have RX and TX queues, but this is not true if
modparam efx_separate_tx_channels=1 is used. In that cases, some
channels only have RX queues and others only TX queues (or more
preciselly, they have them allocated, but not initialized).

Fix efx_channel_has_tx_queues to return the correct value for this case
too.

This has been already done for sfc, do it also for sfc_siena.

1c5de097be net/mlx5: Fix mlx5_get_next_dev() peer device matching
In some use-cases, mlx5 instances will need to search for their peer
device (the other port on the same HCA). For that, mlx5 device matching
mechanism relied on auxiliary_find_device() to search, and used a bad matching
callback function.

This approach has two issues:

1) next_phys_dev() the matching function, assumed all devices are
   of the type mlx5_adev (mlx5 auxiliary device) which is wrong and
   could lead to crashes, this worked for a while, since only lately
   other drivers started registering auxiliary devices.

2) using the auxiliary class bus (auxiliary_find_device) to search for
   mlx5_core_dev devices, who are actually PCIe device instances, is wrong.
   This works since mlx5_core always has at least one mlx5_adev instance
   hanging around in the aux bus.

As suggested by others we can fix 1. by comparing device names prefixes
if they have the string "mlx5_core" in them, which is not a best practice !
but even with that fixed, still 2. needs fixing, we are trying to
match pcie device peers so we should look in the right bus (pci bus),
hence this fix.

The fix:
1) search the pci bus for mlx5 peer devices, instead of the aux bus
2) to validated devices are the same type "mlx5_core_dev" compare if
   they have the same driver, which is bulletproof.

   This wouldn't have worked with the aux bus since the various mlx5 aux
   device types don't share the same driver, even if they share the same device
   wrapper struct (mlx5_adev) "which helped to find the parent device"

f6279f113a net/mlx5e: Update netdev features after changing XDP state
Some features (LRO, HW GRO) conflict with XDP. If there is an attempt to
enable such features while XDP is active, they will be set to `off
[requested on]`. In order to activate these features after XDP is turned
off, the driver needs to call netdev_update_features(). This commit adds
this missing call after XDP state changes.
