Currently the checks are:
[1] unlikely(q->features & IONIC_TXQ_F_HWSTAMP)
[2] !unlikely(q->features & IONIC_TXQ_F_HWSTAMP)
[1] is clear enough, but [2] isn't exactly obvious to the
reader because !unlikely reads as likely. However, that's
not what this means.
[2] means that it's unlikely that the q has
IONIC_TXQ_F_HWSTAMP enabled.
Write an inline helper function to hide the unlikely
optimization to make these checks more readable.

vfree() checks for null internally, so there's no need to
check in the caller. So, always vfree() on variables
allocated with valloc(). If the variables are never
alloc'd vfree() is still safe.

Each time a VF attribute is set via iproute a call to get the VF
configuration is also made. This is currently problematic because for
each VF configuration call there are multiple commands sent to the
device. Unfortunately, this doesn't scale well. Fix this by reporting
the cached VF attributes.
The original change to query the device for getting the VF attributes
f16f5be31009 ("ionic: Query FW when getting VF info via ndo_get_vf_config")
was made to remain consistent with device set VF attributes. However,
after further investigation there is no need to query the device.

Currently ionic_dim_work() is incorrect when in

Our friendly kernel test robot has reminded us that with a new
check we have a warning about a potential string truncation.
In this case it really doesn't hurt anything, but it is worth
addressing especially since there really is no reason to reserve
so many bytes for our queue names. It seems that cutting the
queue name buffer length in half stops the complaint.

Before this change, when operating in polled mode, i.e. no IRQ is
available, every individual C45 access would be hit with a 150us sleep
after the bus access.
For example, on a board with a CN9130 SoC connected to an MV88X3310
PHY, a single C45 read would take around 165us:
root@infix:~$ mdio f212a600.mdio-mii mmd 4:1 bench 0xc003
Performed 1000 reads in 165ms
By replacing the long sleep with a tighter poll loop, we observe a 10x
increase in bus throughput:
root@infix:~$ mdio f212a600.mdio-mii mmd 4:1 bench 0xc003
Performed 1000 reads in 15ms

When flow_indr_dev_register() fails, bnxt_init_tc will free
bp->tc_info through kfree(). However, the caller function
bnxt_init_one() will ignore this failure and call
bnxt_shutdown_tc() on failure of bnxt_dl_register(), where
a use-after-free happens. Fix this issue by setting
bp->tc_info to NULL after kfree().

In __iavf_set_coalesce, the driver checks both ec->rx_coalesce_usecs and
ec->tx_coalesce_usecs for validity. It does this via a chain if if/else-if
blocks. If every single branch of the series of if statements exited, this
would be fine. However, the rx_coalesce_usecs is checked against zero to
print an informative message if use_adaptive_rx_coalesce is enabled. If
this check is true, it short circuits the entire chain of statements,
preventing validation of the tx_coalesce_usecs field.
Indeed, since commit e792779e6b63 ("iavf: Prevent changing static ITR
values if adaptive moderation is on") the iavf driver actually rejects any
change to the tx_coalesce_usecs or rx_coalesce_usecs when
use_adaptive_tx_coalesce or use_adaptive_rx_coalesce is enabled, making
this checking a bit redundant.
Fix this error by removing the unnecessary and redundant checks for
use_adaptive_rx_coalesce and use_adaptive_tx_coalesce. Since zero is a
valid value, and since the tx_coalesce_usecs and rx_coalesce_usecs fields
are already unsigned, remove the minimum value check. This allows assigning
an ITR value ranging from 0-8160 as described by the printed message.

Commit 3a2c6ced90e1 ("i40e: Add a check to see if MFS is set") added
a warning message that reports unexpected size of port's MFS (max
frame size) value. This message use for the port number local
variable 'i' that is wrong.
In i40e_probe() this 'i' variable is used only to iterate VSIs
to find FDIR VSI:
<code>
...
/* if FDIR VSI was set up, start it now */
for (i = 0; i < pf->num_alloc_vsi; i++) {
if (pf->vsi[i] && pf->vsi[i]->type == I40E_VSI_FDIR) {
i40e_vsi_open(pf->vsi[i]);
break;
}
}
...
</code>
So the warning message use for the port number index of FDIR VSI
if this exists or pf->num_alloc_vsi if not.
Fix the message by using 'pf->hw.port' for the port number.

The rvu_dl will be freed in rvu_npa_health_reporters_destroy(rvu_dl)
after the create_workqueue fails, and after that free, the rvu_dl will
be translate back through rvu_npa_health_reporters_create,
rvu_health_reporters_create, and rvu_register_dl. Finally it goes to the
err_dl_health label, being freed again in
rvu_health_reporters_destroy(rvu) by rvu_npa_health_reporters_destroy.
In the second calls of rvu_npa_health_reporters_destroy, however,
it uses rvu_dl->rvu_npa_health_reporter, which is already freed at
the end of rvu_npa_health_reporters_destroy in the first call.
So this patch prevents the first destroy by instantly returning -ENONMEN
when create_workqueue fails. In addition, since the failure of
create_workqueue is the only entrence of label err, it has been
integrated into the error-handling path of create_workqueue.

The E822 hardware for Tx timestamping keeps track of how many
outstanding timestamps are still in the PHY memory block. It will not
generate a new interrupt to the MAC until all of the timestamps in the
region have been read.
If somehow all the available data is not read, but the driver has exited
its interrupt routine already, the PHY will not generate a new interrupt
even if new timestamp data is captured. Because no interrupt is
generated, the driver never processes the timestamp data. This state
results in a permanent failure for all future Tx timestamps.
It is not clear how the driver and hardware could enter this state.
However, if it does, there is currently no recovery mechanism.
Add a recovery mechanism via the periodic PTP work thread which invokes
ice_ptp_periodic_work(). Introduce a new check,
ice_ptp_maybe_trigger_tx_interrupt() which checks the PHY timestamp
ready bitmask. If any bits are set, trigger a software interrupt by
writing to PFINT_OICR.
Once triggered, the main timestamp processing thread will read through
the PHY data and clear the outstanding timestamp data. Once cleared, new
data should trigger interrupts as expected.
This should allow recovery from such a state rather than leaving the
device in a state where we cannot process Tx timestamps.
It is possible that this function checks for timestamp data
simultaneously with the interrupt, and it might trigger additional
unnecessary interrupts. This will cause a small amount of additional
processing.

Due to the cited patch, devlink health commands take devlink lock and
this may result in deadlock for mlx5e_tx_reporter as it takes local
state_lock before calling devlink health report and on the other hand
devlink health commands such as diagnose for same reporter take local
state_lock after taking devlink lock (see kernel log below).
To fix it, remove local state_lock from mlx5e_tx_timeout_work() before
calling devlink_health_report() and take care to cancel the work before
any call to close channels, which may free the SQs that should be
handled by the work. Before cancel_work_sync(), use current_work() to
check we are not calling it from within the work, as
mlx5e_tx_timeout_work() itself may close the channels and reopen as part
of recovery flow.
While removing state_lock from mlx5e_tx_timeout_work() keep rtnl_lock to
ensure no change in netdev->real_num_tx_queues, but use rtnl_trylock()
and a flag to avoid deadlock by calling cancel_work_sync() before
closing the channels while holding rtnl_lock too.

After IPSec TX tables are destroyed, the flow rules in TC rhashtable,
which have the destination to IPSec, are restored to the original
one, the uplink.
However, when the device is in switchdev mode and unload driver with
IPSec rules configured, TC rhashtable cleanup is done before IPSec
cleanup, which means tc_ht->tbl is already freed when walking TC
rhashtable, in order to restore the destination. So add the checking
before walking to avoid unexpected behavior.

Currently eswitch mode_lock is so heavy, for example, it's locked
during the whole process of the mode change, which may need to hold
other locks. As the mode_lock is also used by IPSec to block mode and
encap change now, it is easy to cause lock dependency.
Since some of protections are also done by devlink lock, the eswitch
mode_lock is not needed at those places, and thus the possibility of
lockdep issue is reduced.

IPsec NAT-T packets are UDP encapsulated packets over ESP normal ones.
In case they arrive to RX, the SPI and ESP are located in inner header,
while the check was performed on outer header instead.
That wrong check caused to the situation where received rekeying request
was missed and caused to rekey timeout, which "compensated" this failure
by completing rekeying.

Change normal IPsec flow to use the same creation/destruction functions
for status flow table as that of ESW, which first of all refines the

And more importantly, the ESW status table handles IPsec syndrome
checks at steering by HW, which is more efficient than the previous
behaviour we had where it was copied to WQE meta data and checked
by the driver.

number of 1.
However if user didn't set seq/oseq, the HW used zero as first sequence
