Add macro to get FD(frequency domain) CFO field from ie_type 1, and correct
the naming for preamble CFO field. Each IC could assign the CFO source to
either FD CFO or preamble CFO in chip_info. Based on the suggestion from HW

performance with FD CFO.

Prefer struct_size() over open-coded versions of idiom:
sizeof(struct-with-flex-array) + sizeof(typeof-flex-array-elements) * count
where count is the max number of items the flexible array is supposed to
contain.
In this particular case, in the open-coded version sizeof(typeof-flex-array-elements)
is implicit in _count_ because the type of the flex array data is u8:

Exact location of the crash in __xfrm_state_delete():
if (x->km.seq)
hlist_del_rcu(&x->byseq);
The hlist_node "byseq" was never populated.
The bug only triggers if a new NAT traversal mapping (changed IP or port)
is detected in esp_input_done2() / esp6_input_done2(), which in turn
indirectly calls pfkey_send_new_mapping() *if* the kernel is compiled
with CONFIG_NET_KEY and "af_key" is active.
The PF_KEYv2 message SADB_X_NAT_T_NEW_MAPPING is not part of RFC 2367.
Various implementations have been examined how they handle
the "sadb_msg_seq" header field:
- racoon (Android): does not process SADB_X_NAT_T_NEW_MAPPING
- strongswan: does not care about sadb_msg_seq
- openswan: does not care about sadb_msg_seq
There is no standard how PF_KEYv2 sadb_msg_seq should be populated
for SADB_X_NAT_T_NEW_MAPPING and it's not used in popular
implementations either. Herbert Xu suggested we should just
use the current km.seq value as is. This fixes the root cause
of the oops since we no longer modify km.seq itself.
The update of "km.seq" looks like a copy'n'paste error
from pfkey_send_acquire(). SADB_ACQUIRE must indeed assign a unique km.seq
number according to RFC 2367. It has been verified that code paths
involving pfkey_send_acquire() don't cause the same Oops.

Commit 1229b33973 ("ice: Add low latency Tx timestamp read") refactored
PTP timestamping logic to use a threaded IRQ instead of a separate kthread.
This implementation introduced ice_misc_intr_thread_fn and redefined the
ice_ptp_process_ts function interface to return a value of whether or not
the timestamp processing was complete.
ice_misc_intr_thread_fn would take the return value from ice_ptp_process_ts
and convert it into either IRQ_HANDLED if there were no more timestamps to
be processed, or IRQ_WAKE_THREAD if the thread should continue processing.
This is not correct, as the kernel does not re-schedule threaded IRQ
functions automatically. IRQ_WAKE_THREAD can only be used by the main IRQ
function.
This results in the ice_ptp_process_ts function (and in turn the
ice_ptp_tx_tstamp function) from only being called exactly once per
interrupt.
If an application sends a burst of Tx timestamps without waiting for a
response, the interrupt will trigger for the first timestamp. However,
later timestamps may not have arrived yet. This can result in dropped or
discarded timestamps. Worse, on E822 hardware this results in the interrupt
logic getting stuck such that no future interrupts will be triggered. The
result is complete loss of Tx timestamp functionality.
Fix this by modifying the ice_misc_intr_thread_fn to perform its own
polling of the ice_ptp_process_ts function. We sleep for a few microseconds
between attempts to avoid wasting significant CPU time. The value was
chosen to allow time for the Tx timestamps to complete without wasting so
much time that we overrun application wait budgets in the worst case.
The ice_ptp_process_ts function also currently returns false in the event
that the Tx tracker is not initialized. This would result in the threaded
IRQ handler never exiting if it gets started while the tracker is not
initialized.
Fix the function to appropriately return true when the tracker is not
initialized.
Note that this will not reproduce with default ptp4l behavior, as the
program always synchronously waits for a timestamp response before sending
another timestamp request.

Clear the RGMII_LINK bit upon detecting link down to be consistent with
setting the bit upon link up. We also move the clearing of the
out-of-band disable to the runtime initialization rather than for each
link up/down transition.

I was mistaken how atomic64_try_cmpxchg(&sk_cookie, &res, new)
is working.
I was assuming @res would contain the final sk_cookie value,
regardless of the success of our cmpxchg()
We could do something like:
if (atomic64_try_cmpxchg(&sk_cookie, &res, new)
res = new;
But we can avoid a conditional and read sk_cookie again.
atomic64_cmpxchg(&sk_cookie, res, new);
res = atomic64_read(&sk_cookie);

UAPI:
- Add new GEM_CREATE flags to help to transition more KFD functionality to the DRM UAPI.
These are used internally in the driver to align location based memory coherency
requirements from memory allocated in the KFD with how we manage GPUVM PTEs. They
are currently blocked in the GEM_CREATE IOCTL as we don't have a user right now.
They are just used internally in the kernel driver for now for existing KFD memory
allocations. So a change to the UAPI header, but no functional change in the UAPI.

Currently updating SecY destroys and re-creates RX SA objects,
the re-created RX SA objects are not identical to the destroyed
objects and it disagree on the encryption enabled property which
holds the value false after recreation, this value is not
supported with offload which leads to no traffic after an update.

Before the cited commit, for N channels, a dedicated set of N queues was
created to support XSK, in indices [N, 2N-1], doubling the number of
queues.
In addition, changing the number of channels was prohibited, as it would
shift the indices.
Remove these two leftovers, as we moved XSK to a new queueing scheme,
starting from index 0.

When sync reset now event handling fails on mlx5_pci_link_toggle() then
no reset was done. However, since mlx5_cmd_fast_teardown_hca() was
already done, the firmware function is closed and the driver is left
without firmware functionality.
Fix it by setting device error state and reopen the firmware resources.
Reopening is done by the thread that was called for devlink reload
fw_activate as it already holds the devlink lock.

The cited commit moved from using reformat_id integer to packet_reformat
pointer which introduced the possibility to null pointer dereference.
When setting packet reformat flag and pkt_reformat pointer must
exists so checking MLX5_ESW_DEST_ENCAP is not enough, we need
to make sure the pkt_reformat is valid and check for MLX5_ESW_DEST_ENCAP_VALID.
If the dest encap valid flag does not exists then pkt_reformat can be
either invalid address or null.
Also, to make sure we don't try to access invalid pkt_reformat set it to
null when invalidated and invalidate it before calling add flow code as
its logically more correct and to be safe.

While moving to new CMD API (quiet API), some pre-existing flows may call the new API
function that in case of error, returns the error instead of printing it as previously done.
For such flows we bring back the print but to tracepoint this time for sys admins to
have the ability to check for errors especially for commands using the new quiet API.
