This ensures that the pvid which is stored in __le16 format is converted
to the CPU format. This will fix comparison issues on Big Endian
platforms.

This patch fixes a bug introduced with the addition of the per queue
ITR feature support in ethtool. With that addition, there were
functions added which converted the ITR settings to binary values.
The IS_ENABLED macros that run on those values check whether a bit
is set or not and with the value being binary, the bit check always
returned ITR disabled which prevents any updating of the ITR rate.
This patch fixes the problem by changing the functions to return the
current ITR value instead and renaming it to better reflect
its function. These functions now provide a value which will be
accurately asessed and update the ITR as intended.

When the i40evf_remove() calls netdev close, the device doesn't actually
close - it schedules the work for the watchdog to perform. Since we're
stopping the watchdog, this work doesn't get done. However, we're
resetting the part, so we can free resources after the reset request has
gone through. This plugs a memory leak.

This call is made just prior to running i40e_link_event. In
i40e_link_event, we set hw->phy.get_link_info to true just prior to
calling i40e_get_link_status, which conveniently runs
i40e_update_link_info for us. Thus, we are running i40e_update_link_info

This patch adds a call to the mac_address_write admin q function during
power down to update the PRTPM_SAH/SAL registers with the MC_MAG_EN bit
thus enabling multicast magic packet wakeup.
A FW workaround is needed to write the multicast magic wake up enable
bit in the PRTPM_SAH register. The FW expects the mac address write
admin q cmd to be called first with one of the WRITE_TYPE_LAA flags
and then with the multicast relevant flags.
*Note: This solution only works for X722 devices currently. A PFR will
clear the previously mentioned bit by default, but X722 has support for a
WOL_PRESERVE_ON_PFR flag which prevents the bit from being cleared. Once
other devices support this flag, this solution should work as well.

There exists a bug in which the driver is unable to exit overflow
promiscuous mode after having added "too many" mac filters. It is
expected that after triggering overflow promiscuous, removing the
failed/extra filters should then disable overflow promiscuous mode.
The bug exists because we were intentionally skipping the sync_vsi_filter
path in cases where we were removing failed filters since they shouldn't
have been added to the firmware in the first place, however we still
need to go through the sync_vsi_filter code path to determine whether or
not it is ok to exit overflow promiscuous mode. This patch fixes the
bug by making sure we go through the sync_vsi_filter path in cases of
failed filters.

commit 82e88ff1ea ("hrtimer: Revert CLOCK_MONOTONIC_RAW support") removed
unfortunately a sanity check in the hrtimer code which was part of that
MONOTONIC_RAW patch series.
It would have caught the bogus usage of CLOCK_MONOTONIC_RAW in the wireless
code. So bring it back.
It is way too easy to take any random clockid and feed it to the hrtimer
subsystem. At best, it gets mapped to a monotonic base, but it would be
better to just catch illegal values as early as possible.
Detect invalid clockids, map them to CLOCK_MONOTONIC and emit a warning.
