DHCP frame usually can not be aggregated, but if they go to FISA
path which will require FISA resource support for them, this looks
is not necessary.
Bypass FISA path for RX DHCP frame.

Currently, we register the peer hang notifier when the peer unmap
timer elapses, but do not unregister it. We also pass the peer reference
for which the unmap timeout happened as part of the notifier registry.
Since we do not unregister the notfier, there are chances that we
call the notifier with a stale peer reference during the subsequent
hang event which results in a crash; avoid this by unregistering the
peer hang notifier as part of device recovery.

Currently there is no vdev->osif_rx result check in fisa path,
so if vdev->osif_rx returns failure, the RX skb may not have been
handled and it may be leaked.
Add vdev->osif_rx failure handling to avoid skb leak.

Kernel 5.4 has applied batched GRO_NORMAL packets processing
for all napi_gro_receive() users. this requires NAPI users to
call napi_complete_done() or napi_complete() at the end of every
polling to flush batched GRO_NORMAL packets.
However, by current wlan driver design, napi_gro_recevie()
is not happened in same NAPI polling context and done in another
thread context, it likely packets which have not been flushed from
napi->rx_list will get stall until next RX cycle.
Fix this by adding a manual flushing of the list right after
napi_gro_flush() call to mimic napi_complete() logics.

In case of partial reorder, seq number is sent by FW

from multiple functions. Add update_seq_num flag to make sure that
cur_seq_num_hl updates only during store function.

Because of a race that happen during vdev delete, RX packets can get
queued to the RX thread after the RX flush (done as part of peer deletion)
and by the time RX thread is woken up for processing, the netdev pointer
would be NULL leading to a crash.
Avoid this by dropping pending frames in the RX thread during peer unmap
as well.

Issue happens as below scenaio:
1 suspend happens, but dp_rx_thread didn't finish in time,
so timeout happens for suspend_event, here suspend will
return success to kernel.
2 resume happens before dp_rx_thread to reset resume_event,
and resume finished.
3 if dp_rx_thread finished and blocking with resume_event,
and in following test, suspend didn't come(longer then
hang detect time).
4 hang detect will alarm.
Fix is to return failure if dp_rx_thread can't be suspend
in time. Suspend can triger again later.

Currently, Linux Kernel 4.9 doesn't support WDI3/WDI2 over GSI,
so it missed the definition of is_txr_rn_db_pcie_addr &

for Linux Kernel 4.9 + ROME target. So refine the function
ol_txrx_ipa_wdi_tx_smmu_params to fix compile issue.

Currently many layers store the datapath handles i.e.
pdev and vdev handles and use them for passing as an
argument to the CDP APIs. This gives way to possible

leads to unexpected results.

Currently, sizeof(qdf_dma_addr_t) is 4 bytes, but IPA driver
and WLAN FW always use 8 bytes, we should follow up with them,
otherwise, the numbers of rx complete ring entries will not be
same in both sides. Meanwhile, for tx complete ring, during the
first time initialization, we fill the buffer address with 4
bytes, while GSI FW read 8 bytes address content from tx complete
ring, which should cause the GSI FW get invalid address on the half
way and cause the smmu fault issue. So fill 8 bytes length buffer
address to the tx complete ring can avoid such issue.
