44eb385bc5 octeontx2-af: remove unused cgx_fwi_link_change
The newly added driver causes a warning about a function that is
not used anywhere:

drivers/net/ethernet/marvell/octeontx2/af/cgx.c:320:12: error: 'cgx_fwi_link_change' defined but not used [-Werror=unused-function]

Remove it for now, until a user gets added. If we want to use this
function from another module, we also need a declaration in a header
file, which is currently missing, so it would have to change anyway.

5948185b97 nfp: devlink port split support for 1x100G CXP NIC
This commit makes it possible to use devlink to split the 100G CXP
Netronome into two 40G interfaces. Currently when you ask for 2
interfaces, the math in src/nfp_devlink.c:nfp_devlink_port_split
calculates that you want 5 lanes per port because for some reason
eth_port.port_lanes=10 (shouldn't this be 12 for CXP?). What we really
want when asking for 2 breakout interfaces is 4 lanes per port. This
commit makes that happen by calculating based on 8 lanes if 10 are
present.

5b3a5a14f8 net: ethernet: ti: cpsw: use for mcast entries only host port
In dual-emac mode the cpsw driver sends directed packets, that means
that packets go to the directed port, but an ALE lookup is performed
to determine untagged egress only. It means that on tx side no need
to add port bit for ALE mcast entry mask, and basically ALE entry
for port identification is needed only on rx side.

So, add only host port in dual_emac mode as used directed
transmission, and no need in one more port. For single port boards
and switch mode all ports used, as usual, so no changes for them.
Also it simplifies farther changes.

In other words, mcast entries for dual-emac should behave exactly
like unicast. It also can help avoid leaking packets between ports
with same vlan on h/w level if ports could became members of same vid.

So now, for instance, if mcast address 33:33:00:00:00:01 is added then
entries in ALE table:

vid = 1, addr = 33:33:00:00:00:01, port_mask = 0x1
vid = 2, addr = 33:33:00:00:00:01, port_mask = 0x1

Instead of:
vid = 1, addr = 33:33:00:00:00:01, port_mask = 0x3
vid = 2, addr = 33:33:00:00:00:01, port_mask = 0x5

With the same considerations, set only host port for unregistered
mcast for dual-emac mode in case of IFF_ALLMULTI is set, exactly like
it's done in cpsw_ale_set_allmulti().

Whenever kernel or user decides to call rx mode update, it clears
every multicast entry from forwarding table and in some time adds
it again. This time can be enough to drop incoming multicast packets.

That's why clear only staled multicast entries and update or add new

9f9a742db4 FDDI: defza: Support capturing outgoing SMT traffic
DEC FDDIcontroller 700 (DEFZA) uses a Tx/Rx queue pair to communicate
SMT frames with adapter's firmware.  Any SMT frame received from the RMC
via the Rx queue is queued back by the driver to the SMT Rx queue for
the firmware to process.  Similarly the firmware uses the SMT Tx queue
to supply the driver with SMT frames which are queued back to the Tx
queue for the RMC to send to the ring.

When a network tap is attached to an FDDI interface handled by `defza'
any incoming SMT frames captured are queued to our usual processing of
network data received, which in turn delivers them to any listening
taps.

However the outgoing SMT frames produced by the firmware bypass our
network protocol stack and are therefore not delivered to taps.  This in
turn means that taps are missing a part of network traffic sent by the
adapter, which may make it more difficult to track down network problems
or do general traffic analysis.

Call `dev_queue_xmit_nit' then in the SMT Tx path, having checked that
a network tap is attached, with a newly-created `dev_nit_active' helper
wrapping the usual condition used in the transmit path.

61414f5ec9 FDDI: defza: Add support for DEC FDDIcontroller 700 TURBOchannel adapter
Add support for the DEC FDDIcontroller 700 (DEFZA), Digital Equipment
Corporation's first-generation FDDI network interface adapter, made for
TURBOchannel and based on a discrete version of what eventually became
Motorola's widely used CAMEL chipset.

The CAMEL chipset is present for example in the DEC FDDIcontroller
TURBOchannel, EISA and PCI adapters (DEFTA/DEFEA/DEFPA) that we support
with the `defxx' driver, however the host bus interface logic and the
firmware API are different in the DEFZA and hence a separate driver is
required.

There isn't much to say about the driver except that it works, but there
is one peculiarity to mention.  The adapter implements two Tx/Rx queue
pairs.

Of these one pair is the usual network Tx/Rx queue pair, in this case
used by the adapter to exchange frames with the ring, via the RMC (Ring
Memory Controller) chip.  The Tx queue is handled directly by the RMC
chip and resides in onboard packet memory.  The Rx queue is maintained
via DMA in host memory by adapter's firmware copying received data
stored by the RMC in onboard packet memory.

The other pair is used to communicate SMT frames with adapter's
firmware.  Any SMT frame received from the RMC via the Rx queue must be
queued back by the driver to the SMT Rx queue for the firmware to
process.  Similarly the firmware uses the SMT Tx queue to supply the
driver with SMT frames that must be queued back to the Tx queue for the
RMC to send to the ring.

This solution was chosen because the designers ran out of PCB space and
could not squeeze in more logic onto the board that would be required to
handle this SMT frame traffic without the need to involve the driver, as
with the later DEFTA/DEFEA/DEFPA adapters.

Finally the driver does some Frame Control byte decoding, so to avoid
magic numbers some macros are added to <linux/if_fddi.h>.

df52eab23d tun: Consistently configure generic netdev params via rtnetlink
Configuring generic network device parameters on tun will fail in
presence of IFLA_INFO_KIND attribute in IFLA_LINKINFO nested attribute
since tun_validate() always return failure.

This can be visualized with following ip-link(8) command sequences:

  # ip link set dev tun0 group 100
  # ip link set dev tun0 group 100 type tun
  RTNETLINK answers: Invalid argument

with contrast to dummy and veth drivers:

  # ip link set dev dummy0 group 100
  # ip link set dev dummy0 type dummy

  # ip link set dev veth0 group 100
  # ip link set dev veth0 group 100 type veth

Fix by returning zero in tun_validate() when @data is NULL that is
always in case since rtnl_link_ops->maxtype is zero in tun driver.

d49c88d767 r8169: Enable MSI-X on RTL8106e
Originally, we have an issue where r8169 MSI-X interrupt is broken after
S3 suspend/resume on RTL8106e of ASUS X441UAR.

	Capabilities: [170] Latency Tolerance Reporting
	Kernel driver in use: r8169
	Kernel modules: r8169

We found the all of the values in PCI BAR=4 of the ethernet adapter
become 0xFF after system resumes.  That breaks the MSI-X interrupt.
Therefore, we can only fall back to MSI interrupt to fix the issue at
that time.

However, there is a commit which resolves the drivers getting nothing in
PCI BAR=4 after system resumes.  It is 04cb3ae895d7 "PCI: Reprogram
bridge prefetch registers on resume" by Daniel Drake.

After apply the patch, the ethernet adapter works fine before suspend
and after resume.  So, we can revert the workaround after the commit
"PCI: Reprogram bridge prefetch registers on resume" is merged into main
tree.

This patch reverts commit 7bb05b85bc2d1a1b647b91424b2ed4a18e6ecd81
"r8169: don't use MSI-X on RTL8106e".

ba94c753cc ath10k: add QMI message handshake for wcn3990 client
Add WCN3990 QMI client handshakes for Q6 integrated WLAN connectivity
subsystem. This layer is responsible for communicating qmi control
messages to wifi fw QMI service using QMI messaging protocol.

Qualcomm MSM Interface(QMI) is a messaging format used to communicate
between components running between remote processors with underlying
transport layer based on integrated chipset(shared memory) or
discrete chipset(PCI/USB/SDIO/UART).

72569b7be4 ath9k: fix RX_STAT_INC() etc macros
A couple of macros that deal with statistics in ath9k rely on the
declaration of the 'sc' variable, which they dereference.

However, when the statistics are disabled, the new instance in
ath_cmn_process_fft() causes a warning for an unused variable:

drivers/net/wireless/ath/ath9k/common-spectral.c: In function 'ath_cmn_process_fft':
drivers/net/wireless/ath/ath9k/common-spectral.c:474:20: error: unused variable 'sc' [-Werror=unused-variable]

It's better if those macros only operate on their arguments instead of
known variable names, and adding a cast to (void) kills off that warning.

0738b4998c ath10k: allocate small size dma memory in ath10k_pci_diag_write_mem
ath10k_pci_diag_write_mem may allocate big size of the dma memory
based on the parameter nbytes. Take firmware diag download as
example, the biggest size is about 500K. In some systems, the
allocation is likely to fail because it can't acquire such a large
contiguous dma memory.

The fix is to allocate a small size dma memory. In the loop,
driver copies the data to the allocated dma memory and writes to
the destination until all the data is written.

Tested with QCA6174 PCI with
firmware-6.bin_WLAN.RM.4.4.1-00119-QCARMSWP-1, this also affects
QCA9377 PCI.

ce834e280f ath10k: support NET_DETECT WoWLAN feature
For WoWLAN support it is expected to support wake up based on discovery of
one or more known SSIDs. This is the WIPHY_WOWLAN_NET_DETECT feature,
which shows up as an NL80211 feature flag.

This shows up in 'iw phy' as:

WoWLAN support:
* wake up on network detection, up to 16 match sets

And it can be enabled with command:

iw phy0 wowlan enable net-detect interval 5000 delay 30 freqs 2412 matches ssid foo

Firmware will do scan by the configured parameters after suspend and
wakeup if it found matched SSIDs. Tested with QCA6174 hw3.0 with
firmware WLAN.RM.4.4.1-00110-QCARMSWPZ-1.

Currently the wmi command for setting probe request
oui, needed for mac randomization, is sent during
the mac register. At this time, during the driver
init the wmi has already been detached. This can
cause unexpected behavior since the firmware is
already down and the wmi has been detached.

Send the wmi command for setting probe request
oui during the driver start. This will make sure
that the firmware is started and wmi is initialized
before we send this command.
