Checking the relevant rxd bits for the checksum information only indicates
if the checksum verification was performed by the hardware and doesn't show
actual checksum errors. Checksum errors are indicated in the info field of
the DMA descriptor. Fix packets erroneously marked as CHECKSUM_UNNECESSARY
by checking the extra bits as well.
Those bits are only passed to the driver for MMIO devices at the moment, so
limit checksum offload to those.

Group 3 in RxD is disabled in monitor mode. We should use the group 5 in
RxD instead to fix antenna signal way off issue, e.g we would see the
incorrect antenna signal value in wireshark. On the other hand, Group 5
wouldn't be used in STA or AP mode, so the patch shouldn't cause any

It is unexpected that the reset work is running simultaneously with
the suspend or resume context and it is possible that reset work is still
running even after mt7921 is suspended if we don't fix the race issue.
Thus, the suspend procedure should be waiting until the reset is completed
at the beginning and ignore the subsequent the reset requests.
In case there is an error that happens during either suspend or resume
handler, we will schedule a reset task to recover the error before
returning the error code to ensure we can immediately fix the error there.

Previously the code used skb_set_queue_mapping for management or non-bufferable

This can confuse AQL, which expects the value to remain the same until the tx
