__hdd_tx_timeout passes cdp_soc context dump_flow_pool_info callback
function. Lithium_dp interchangeably use cdp_soc and dp_soc as cdp_soc is

Same is not valid for iHelium datapath, do not expect caller to pass
the txrx_pdev context, instead get it from global cds_context.

The use TAILQ_FOREACH for freeing the fw_stats list during
pdev detach causes a use-after-free condition, which can lead
to unexpected behavior during the driver load or unload.
Fix the possible Use-after-free condition in pdev detach, by
using TAILQ_FOREACH_SAFE instead of TAILQ_FOREACH for freeing
the fw_stats list.

GRO aggregations are hanging out of NAPI instance and We cannot use the
hif NAPI instance in Rx thread as gro_list inside NAPI is flushed out
at the start and end of NAPI poll, this will corrupt the gro_list on
which rx_thread is working. Address this concern by creating dummy
NAPI instances mapping to each hif NAPI and not scheduling them.

wdi2.0 feature adds extra 2 bytes to frag_header and thus hdr_len
to IPA HW also adds 2 bytes. This change breaks pre-wdi2.0 platform
with WiFi FW discarding all TX traffic since packet payload is
with an extra 2-byte offset.
Fix is to add frag_header structure with pre-wdi2.0 pattern.

Remove panic after peer_delete timeout and fail corresponding peer

to delay in releasing reference. This delay cannot be completely
removed, hence rather than panic after timeout, enhance logging and
fail corresponding peer operation.

There is a very rare race condition between
ol_txrx_peer_find_by_local_id_inc_ref(running in OL RX
thread context) and ol_txrx_peer_detach(running in MC
thread context) where MC thread 1st got chance and cleared
the peer->valid flag before OL RX thread can increment the
ref count and this led to OL RX thread got a peer without
any ref count which was freed later while OL RX thread was
still using it.
Change:
1 Set peer to NULL if peer valid check fails in
ol_txrx_peer_find_by_local_id_inc_ref
2 release peer ref cnt for error case in ol_rx_data_cb
