The mlx5 IPsec code has logical separation between code that operates
with XFRM objects (ipsec.c), HW objects (ipsec_offload.c), flow steering
logic (ipsec_fs.c) and data path (ipsec_rxtx.c).
Such separation makes sense for C-files, but isn't needed at all for
H-files as they are included in batch anyway.

mlx5 IPsec code updated ESN through workqueue with allocation calls
in the data path, which can be saved easily if the work is created
during XFRM state initialization routine.
The locking used later in the work didn't protect from anything because
change of HW context is possible during XFRM state add or delete only,
which can cancel work and make sure that it is not running.

The XFRM code performs fallback to software IPsec if .xdo_dev_state_add()
returns -EOPNOTSUPP. This is what mlx5 did very deep in its stack trace,
despite have all the knowledge that IPsec is not going to work in very
early stage.
This is achieved by making sure that priv->ipsec pointer is valid for
fully working and supported hardware crypto IPsec engine.
In case, the hardware IPsec is not supported, the XFRM code will set NULL
to xso->dev and it will prevent from calls to various .xdo_dev_state_*()
callbacks.

In bnxt_poll_p5(), we first check cpr->has_more_work. If it is true,
we are in NAPI polling mode and we will call __bnxt_poll_cqs() to
continue polling. It is possible to exhanust the budget again when
__bnxt_poll_cqs() returns.
We then enter the main while loop to check for new entries in the NQ.
If we had previously exhausted the NAPI budget, we may call
__bnxt_poll_work() to process an RX entry with zero budget. This will
cause packets to be dropped unnecessarily, thinking that we are in the
netpoll path. Fix it by breaking out of the while loop if we need
to process an RX NQ entry with no budget left. We will then exit
NAPI and stay in polling mode.

bnxt_open() can fail in this code path, especially on a VF when
it fails to reserve default rings:
bnxt_open()
__bnxt_open_nic()
bnxt_clear_int_mode()
bnxt_init_dflt_ring_mode()
RX rings would be set to 0 when we hit this error path.
It is possible for a subsequent bnxt_open() call to potentially succeed
with a code path like this:
bnxt_open()
bnxt_hwrm_if_change()
bnxt_fw_init_one()
bnxt_fw_init_one_p3()
bnxt_set_dflt_rfs()
bnxt_rfs_capable()
bnxt_hwrm_reserve_rings()
On older chips, RFS is capable if we can reserve the number of vnics that
is equal to RX rings + 1. But since RX rings is still set to 0 in this
code path, we may mistakenly think that RFS is supported for 0 RX rings.
Later, when the default RX rings are reserved and we try to enable
RFS, it would fail and cause bnxt_open() to fail unnecessarily.
We fix this in 2 places. bnxt_rfs_capable() will always return false if
RX rings is not yet set. bnxt_init_dflt_ring_mode() will call
bnxt_set_dflt_rfs() which will always clear the RFS flags if RFS is not
supported.

The AlphaProject AP-SH4A-3A/AP-SH4AD-0A SH boards use IRQ0 for their SMSC
LAN911x Ethernet chip, so the networking on them must have been broken by
commit 965b2aa78fbc ("net/smsc911x: fix irq resource allocation failure")
which filtered out 0 as well as the negative error codes -- it was kinda
correct at the time, as platform_get_irq() could return 0 on of_irq_get()
failure and on the actual 0 in an IRQ resource. This issue was fixed by
me (back in 2016!), so we should be able to fix this driver to allow IRQ0
usage again...
When merging this to the stable kernels, make sure you also merge commit
e330b9a6bb35 ("platform: don't return 0 from platform_get_irq[_byname]()
on error") -- that's my fix to platform_get_irq() for the DT platforms...

As noted elsewhere, various GPON SFP modules exhibit non-standard
TX-fault behaviour. In the tested case, the Huawei MA5671A, when used
in combination with a Marvell mv88e6085 switch, was found to
persistently assert TX-fault, resulting in the module being disabled.
This patch adds a quirk to ignore the SFP_F_TX_FAULT state, allowing the
module to function.

1) Trivial Misc updates to mlx5 driver
2) From Mark Bloch: Flow steering, general steering refactoring/cleaning
An issue with flow steering deletion flow (when creating a rule without
dests) turned out to be easy to fix but during the fix some issue
with the flow steering creation/deletion flows have been found.
The following patch series tries to fix long standing issues with flow
steering code and hopefully preventing silly future bugs.
A) Fix an issue where a proper dest type wasn't assigned.
B) Refactor and fix dests enums values, refactor deletion
function and do proper bookkeeping of dests.
C) Change mlx5_del_flow_rules() to delete rules when there are no
no more rules attached associated with an FTE.
D) Don't call hard coded deletion function but use the node's
defined one.
E) Add a WARN_ON() to catch future bugs when an FTE with dests
is deleted.

Spectrum machines have two resources related to keeping packets in an
internal buffer: bytes (allocated in cell-sized units) for packet payload,
and descriptors, for keeping metadata. Currently, mlxsw only configures the
bytes part of the resource management.
Spectrum switches permit a full parallel configuration for the descriptor
resources, including port-pool and port-TC-pool quotas. By default, these
are all configured to use pool 14, with an infinite quota. The ingress pool
14 is then infinite in size.
However, egress pool 14 has finite size by default. The size is chip
dependent, but always much lower than what the chip actually permits. As a
result, we can easily construct workloads that exhaust the configured
descriptor limit.
Fix the issue by configuring the egress descriptor pool to be infinite in
size as well. This will maintain the configuration philosophy of the
default configuration, but will unlock all chip resources to be usable.
In the code, include both the configuration of ingress and ingress, mostly
for clarity.

DPK is short for digital pre-distortion calibration. It can adjusts digital
waveform according to PA linear characteristics dynamically to enhance
TX EVM.
Do this calibration when we are going to run on AP channel. To prevent
power offset out of boundary, it monitors thermal and set proper boundary
to register.
8852c needs two backup buffers, so we enlarge the array. But, 8852a still
needs only one, so it only uses first element (index zero).

TSSI is transmitter signal strength indication, which is a close-loop
hardware circuit to feedback actual transmitting power as a reference for
next transmission.
When we setup channel to connect an AP, it does full calibration. When
switching bands or channels, it needs to reset hardware status to prevent
use wrong feedback of previous transmission.
To do TX power compensation reflecting current temperature, it loads tables
of compensation values into registers according to channel and band group.

Print the initializing field in case of FW couldn't initialize before
timeout. This will help to better understand the root cause in some
cases.

Runtime devlink params always read their values from the get() callbacks.
Also, it is an error to set driverinit_value for params which don't
support driverinit cmode. Delete such assignments.
In addition, move the set of default matching mode inside eswitch code.

The memory of spec is allocated with kvzalloc(), the corresponding
release function should not be kfree(), use kvfree() instead.

Current memory failure code in the debugfs returns -ENOSPC. This is
normally used for indicating that there is no space left on the
device and is not applicable for memory allocation failures.
Replace this with -ENOMEM.

====================
pull-request: ieee802154-next 2022-05-01
Miquel Raynal landed two patch series bundled in this pull request.
The first series re-works the symbol duration handling to better
accommodate the needs of the various phy layers in ieee802154.
In the second series Miquel improves th errors handling from drivers
up mac802154. THis streamlines the error handling throughout the
ieee/mac802154 stack in preparation for sync TX to be introduced for
MLME frames.

Defining local versions of NAPI_POLL_WEIGHT with the same
values in the drivers just makes refactoring harder.

If the previous list_for_each_entry_continue_rcu() don't exit early
(no goto hit inside the loop), the iterator 'cvif' after the loop
will be a bogus pointer to an invalid structure object containing
the HEAD (&ar->vif_list). As a result, the use of 'cvif' after that
will lead to a invalid memory access (i.e., 'cvif->id': the invalid
pointer dereference when return back to/after the callsite in the
carl9170_update_beacon()).
The original intention should have been to return the valid 'cvif'
when found in list, NULL otherwise. So just return NULL when no
entry found, to fix this bug.

The comment next to WIL6210_NAPI_BUDGET says "arbitrary".
If we're picking arbitrary values let's pick the recommended
default which is NAPI_POLL_WEIGHT.
