CPT HW would trigger the CPT AF FLT interrupt when CPT engines
hits some uncorrectable errors and AF is the one which receives
the interrupt and recovers the engines.
This patch adds a mailbox for CPT VFs to request for CPT faulted
and recovered engines info.

The CN10K CPT coprocessor contains a context processor
to accelerate updates to the IPsec security association
contexts. The context processor contains a context cache.
This patch updates CPT LF ALLOC mailbox to config ctx_ilen
requested by VFs. CPT_LF_ALLOC:ctx_ilen is the size of
initial context fetch.

CN10K CPT coprocessor includes a component named RXC which
is responsible for reassembly of inner IP packets. RXC has
the feature to evict oldest entries based on age/threshold.
The age/threshold is being set to minimum values to evict
all entries at the time of teardown.
This patch adds code to restore timeout and threshold config
after teardown sequence is complete as it is global config.

On OcteonTX2 platform CPT instruction enqueue is only
possible via LMTST operations.
The existing FLR sequence mentioned in HRM requires
a dummy LMTST to CPT but LMTST can't be submitted from
AF driver. So, HW team provided a new sequence to avoid
dummy LMTST. This patch adds code for the same.

====================
dsa: lan9303: Move to PHYLINK
This patch series moves the lan9303 driver to use the phylink
api away from phylib.
Migrating to phylink means removing the .adjust_link api. The
functionality from the adjust_link is moved to the phylink_mac_link_up
api. The code being removed only affected the cpu port. The other
ports on the LAN9303 do not need anything from the phylink_mac_link_up
api.
Patches:
0001 - Whitespace only change aligning the dsa_switch_ops members.
No code changes.
0002 - Moves the Turbo bit initialization out of the adjust_link api and
places it in a driver initialization execution path. It only needs
to be initialized once, it is never changed, and it is not a
per-port flag.
0003 - Adds exception handling logic in the extremely unlikely event that
the read of the device fails.
0004 - Performance optimization that skips a slow register write if there
is no need to perform it.
0005 - Change the way we identify the xMII port as phydev will be NULL
when this logic is moved into phylink_mac_link_up.
0006 - Removes adjust_link and begins using the phylink dsa_switch_ops
apis.
0007 - Adds XMII port flow control settings in the phylink_mac_link_up()
api while cleaning up the ANEG / speed / duplex implementation.
---
v6->v7:
- Moved the initialization of the Turbo bit into lan9303_setup().
- Added a macro for determining is a port is an XMII port.
- Added setting the XMII flow control in the phylink_mac_link_up() API.
- removed unnecessary error handling and cleaned up the code flow in
phylink_mac_link_up().
v5->v6:
- Moved to using port number to identify xMII port for the LAN9303.
v4->v5:
- Created prep patches to better show how things migrate.
- cleaned up comments.
v3->v4:
- Addressed whitespace issues as a separate patch.
- Removed port_max_mtu api patch as it is unrelated to phylink migration.
- Reworked the implementation to preserve the adjust_link functionality
by including it in the phylink_mac_link_up api.
v2->v3:
Added back in disabling Turbo Mode on the CPU MII interface.
Removed the unnecessary clearing of the phy supported interfaces.
v1->v2:
corrected the reported mtu size, removing ETH_HLEN and ETH_FCS_LEN

This is not actually creating a real problem because the path leading to
'val' being used uninitialized will eventually override the full content
of that variable before actually using it for writing the register.
However, the fix is simple and comes at basically no cost.

The fact that devlink instance lock is held over mlx5 auxiliary devices
probe and remove routines brought a need to conditionally take devlink
instance lock there. The code is checking a MLX5E_LOCKED_FLOW flag
in mlx5 priv struct.
This is racy and may lead to access devlink objects without holding
instance lock or deadlock.
To avoid this, the only lock-wise sane solution is to make the
devlink entities created by the auxiliary device independent on
the original pci devlink instance. Create devlink instance for the
auxiliary device and put the uplink port instance there alongside with
the port health reporters.

In the am65_cpsw_init_serdes_phy() function, the error handling for the
call to the devm_of_phy_get() function misses the case where the return
value of devm_of_phy_get() is ERR_PTR(-EPROBE_DEFER). Proceeding without
handling this case will result in a crash when the "phy" pointer with
this value is dereferenced by phy_init() in am65_cpsw_enable_phy().
Fix this by adding appropriate error handling code.

These are WiFi 7 devices that will be introduced into the market
in 2023, with new drivers. Wireless extensions haven't been in
real development since 2006. Since wireless has evolved a lot,
and continues to evolve significantly with Multi-Link Operation,
there's really no good way to still support wireless extensions
for devices that do MLO.
Stop supporting wireless extensions for new devices. We don't
consider this a regression since no such devices (apart from
hwsim) exist yet.

With WiFi 7 (802.11ax, MLO/EHT) around the corner, we're going to
remove support for wireless extensions with new devices since MLO
(multi-link operation) cannot be properly indicated using them.
Add a warning to indicate which processes are still using wireless
extensions, if being used with modern (i.e. cfg80211) drivers.

Pull zonefs fix from Damien Le Moal:
- A single patch to fix sync write operations to detect and handle
errors due to external zone corruptions resulting in writes at
invalid location, from me.

ALU table entry 2 register in KSZ9477 have bit positions reserved for
forwarding port map. This field is referred in ksz9477_fdb_del() for
clearing forward port map and alu table.
But current fdb_del refer ALU table entry 3 register for accessing forward
port map. Update ksz9477_fdb_del() to get forward port map from correct
alu table entry register.
With this bug, issue can be observed while deleting static MAC entries.
Delete any specific MAC entry using "bridge fdb del" command. This should
clear all the specified MAC entries. But it is observed that entries with
self static alone are retained.
Tested on LAN9370 EVB since ksz9477_fdb_del() is used common across
LAN937x and KSZ series.

Avoid race between process wakeup and tpacket_v3 block timeout.
The test waits for cfg_timeout_msec for packets to arrive. Packets
arrive in tpacket_v3 rings, which pass packets ("frames") to the
process in batches ("blocks"). The sk waits for req3.tp_retire_blk_tov
msec to release a block.
Set the block timeout lower than the process waiting time, else
the process may find that no block has been released by the time it
scans the socket list. Convert to a ring of more than one, smaller,
blocks with shorter timeouts. Blocks must be page aligned, so >= 64KB.

The referenced commit changed the error code returned by the kernel
when preventing a non-established socket from attaching the ktls
ULP. Before to such a commit, the user-space got ENOTCONN instead
of EINVAL.
The existing self-tests depend on such error code, and the change
caused a failure:
RUN global.non_established ...
tls.c:1673:non_established:Expected errno (22) == ENOTCONN (107)
non_established: Test failed at step #3
FAIL global.non_established
In the unlikely event existing applications do the same, address
the issue by restoring the prior error code in the above scenario.
Note that the only other ULP performing similar checks at init
time - smc_ulp_ops - also fails with ENOTCONN when trying to attach
the ULP to a non-established socket.
