The multi-chip module MT7530 switch with a 40 MHz oscillator on the
MT7621AT, MT7621DAT, and MT7621ST SoCs forwards corrupt frames using
trgmii.
This is caused by the assumption that MT7621 SoCs have got 150 MHz PLL,
hence using the ncpo1 value, 0x0780.
My testing shows this value works on Unielec U7621-06, Bartel's testing
shows it won't work on Hi-Link HLK-MT7621A and Netgear WAC104. All devices
tested have got 40 MHz oscillators.
Using the value for 125 MHz PLL, 0x0640, works on all boards at hand. The
definitions for 125 MHz PLL exist on the Banana Pi BPI-R2 BSP source code
whilst 150 MHz PLL don't.
Forwarding frames using trgmii on the MCM MT7530 switch with a 25 MHz
oscillator on the said MT7621 SoCs works fine because the ncpo1 value
defined for it is for 125 MHz PLL.
Change the 150 MHz PLL comment to 125 MHz PLL, and use the 125 MHz PLL
ncpo1 values for both oscillator frequencies.

igc_configure_rx_ring() function will be called as part of XDP program
setup. If Rx hardware timestamp is enabled prio to XDP program setup,
this timestamp enablement will be overwritten when buffer size is
written into SRRCTL register.
Thus, this commit read the register value before write to SRRCTL
register. This commit is tested by using xdp_hw_metadata bpf selftest
tool. The tool enables Rx hardware timestamp and then attach XDP program
to igc driver. It will display hardware timestamp of UDP packet with
port number 9092. Below are detail of test steps and results.
Command on DUT:
sudo ./xdp_hw_metadata <interface name>
Command on Link Partner:
echo -n skb | nc -u -q1 <destination IPv4 addr> 9092
Result before this patch:

Result after this patch:
found skb hwtstamp = 1677800973.642836757
Optionally, read PHC to confirm the values obtained are almost the same:

It is not possible to set the number of lanes when setting link modes
using the legacy IOCTL ethtool interface. Since 'struct
ethtool_link_ksettings' is not initialized in this path, drivers receive
an uninitialized number of lanes in 'struct
ethtool_link_ksettings::lanes'.
When this information is later queried from drivers, it results in the
ethtool code making decisions based on uninitialized memory, leading to
the following KMSAN splat [1]. In practice, this most likely only
happens with the tun driver that simply returns whatever it got in the
set operation.
As far as I can tell, this uninitialized memory is not leaked to user
space thanks to the 'ethtool_ops->cap_link_lanes_supported' check in
linkmodes_prepare_data().
Fix by initializing the structure in the IOCTL path. Did not find any
more call sites that pass an uninitialized structure when calling
'ethtool_ops::set_link_ksettings()'.

Through testing I found out that hardware vlan rx offload support seems to
have some hardware issues. At least when using multiple MACs and when
receiving tagged packets on the secondary MAC, the hardware can sometimes
start to emit wrong tags on the first MAC as well.
In order to avoid such issues, drop the feature configuration and use
the offload feature only for DSA hardware untagging on MT7621/MT7622
devices where this feature works properly.

rxrpc: Timeout handling fixes
Here are three patches to fix timeouts handling in AF_RXRPC:
(1) The hard call timeout should be interpreted in seconds, not
milliseconds.
(2) Allow a waiting call to be aborted (thereby cancelling the call) in
the case a signal interrupts sendmsg() and leaves it hanging until it
is granted a channel on a connection.
(3) Kernel-generated calls get the timer started on them even if they're
still waiting to be attached to a connection. If the timer expires
before the wait is complete and a conn is attached, an oops will
occur.

afs_make_call() calls rxrpc_kernel_begin_call() to begin a call (which may
get stalled in the background waiting for a connection to become
available); it then calls rxrpc_kernel_set_max_life() to set the timeouts -
but that starts the call timer so the call timer might then expire before
we get a connection assigned - leading to the following oops if the call
stalled:

Fix this by noting the timeouts in struct rxrpc_call when the call is
created. The timer will be started when the first packet is transmitted.
It shouldn't be possible to trigger this directly from userspace through
AF_RXRPC as sendmsg() will return EBUSY if the call is in the
waiting-for-conn state if it dropped out of the wait due to a signal.

When sendmsg() creates an rxrpc call, it queues it to wait for a connection
and channel to be assigned and then waits before it can start shovelling
data as the encrypted DATA packet content includes a summary of the
connection parameters.
However, sendmsg() may get interrupted before a connection gets assigned
and further sendmsg() calls will fail with EBUSY until an assignment is
made.
Fix this so that the call can at least be aborted without failing on
EBUSY. We have to be careful here as sendmsg() mustn't be allowed to start
the call timer if the call doesn't yet have a connection assigned as an
oops may follow shortly thereafter.

The feature of flow control becomes abnormal, if the device sends a
pause frame and the tx/rx is disabled before sending a release frame. It
causes the lost of packets.
Set PLA_RX_FIFO_FULL and PLA_RX_FIFO_EMPTY to zeros before disabling the
tx/rx. And, toggle FC_PATCH_TASK before enabling tx/rx to reset the flow
control patch and timer. Then, the hardware could clear the state and
the flow control becomes normal after enabling tx/rx.
Besides, remove inline for fc_pause_on_auto() and fc_pause_off_auto().

There are cases where the device is adminstratively UP, but operationally
down. For example, we have a physical device (Nvidia ConnectX-6 Dx, 25Gbps)
who's cable was pulled out, here is its ip link output:
5: ens2f1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
link/ether b8:ce:f6:4b:68:35 brd ff:ff:ff:ff:ff:ff
altname enp179s0f1np1
As you can see, it's administratively UP but operationally down.
In this case, sending a packet to this port caused a nasty kernel hang (so
nasty that we were unable to capture it). Aborting a transmit based on
operational status (in addition to administrative status) fixes the issue.

On some distributions, the rp_filter is automatically set (=1) by
default on a netdev basis (also on VRFs).
In an SRv6 End.DT46 behavior, decapsulated IPv4 packets are routed using
the table associated with the VRF bound to that tunnel. During lookup
operations, the rp_filter can lead to packet loss when activated on the
VRF.
Therefore, we chose to make this selftest more robust by explicitly
disabling the rp_filter during tests (as it is automatically set by some
Linux distributions).

David Ahern reported crashes in skb_copy_ubufs() caused by TCP tx zerocopy
using hugepages, and skb length bigger than ~68 KB.
skb_copy_ubufs() assumed it could copy all payload using up to
MAX_SKB_FRAGS order-0 pages.
This assumption broke when BIG TCP was able to put up to 512 KB per skb.
We did not hit this bug at Google because we use CONFIG_MAX_SKB_FRAGS=45

A solution is to use higher order pages if needed.

Macsec fixes for CN10KB
This patch set has fixes for the issues encountered while
testing macsec on CN10KB silicon. Below is the description
of patches:
Patch 1: For each LMAC two MCSX_MCS_TOP_SLAVE_CHANNEL_CFG registers exist
in CN10KB. Bypass has to be disabled in two registers.
Patch 2: Add workaround for errata w.r.t accessing TCAM DATA and MASK registers.
Patch 3: Fixes the parser configuration to allow PTP traffic.
Patch 4: Addresses the IP vector and block level interrupt mask changes.
Patch 5: Fix NULL pointer crashes when rebooting
Patch 6: Since MCS is global block shared by all LMACS the TCAM match
must include macsec DMAC also to distinguish each macsec interface
Patch 7: Before freeing MCS hardware resource to AF clear the stats also.
Patch 8: Stats which share single counter in hardware are tracked in software.
This tracking was based on wrong secy mode params.
Use correct secy mode params
Patch 9: When updating secy mode params, PN number was also reset to
initial values. Hence do not write to PN value register when
updating secy.
