Currently the EAPOL/ARP/DHCP frames arriving as 2K-jump
or out-of-order frmaes are being delivered to the network
stack, without checking for the packet-number sequence.
WCN7850 has hardware support to provide the packet number
of the previous successful re-ordered packet from hardware.
Use this feature to check if the packet-number are in proper
sequence for these EAPOL/ARP/DHCP packets arriving as 2k-jump
or out-of-order packets before submitting it to the network
stack.

WCN7850 has support for near full indication for

preventive actions to avoid ring full watchdog irq
trigger.

Smart monitor mode requires buffers on monitor status ring only.
It does not require any buffers on monitor buffer ring.
As an optimization, initialization of descriptor pool and allocation
of buffers for monitor buffer ring is not required. Also filter
settings for monitor buffer ring are not required in smart monitor
mode.

In case of aging out wds entries, avoid sending all
the wds delete wmi commands in a huge single burst.
Instead limit the maximum commands to half of the
wmi queue size. Inactivity will continue to be
marked every 120 secs but the inactive entries
will be flushed every 5 secs if there are pending
entries.

Memory allocated for tx_hw_desc_history uses incorrect
size parameter resulting in much lower memory to get
assigned. This will result in OOB access and corruptions
in memory, regions post the trailing boundary when updating
tx hw desc events via dp_tx_hw_desc_update_evt.
Fix is to use the appropriate memory size for tx_hw_desc_history
and add NULL check in dp_tx_hw_desc_update_evt.

As per current design, in failure path of hdd_wlan_start_modules,
mem_free of hif_ext_group is done (in cds_dp_close) before
free_irq (in hdd_hif_close), during next hdd_wlan_start_modules,
request_irq adds new handler entry to the list in irq_desc, this
leads to a crash on accessing older stale entry from irq handler,
so adding a bus_ops hif_grp_irq_deconfigure to free ext grp IRQs.

There is a timing race condition between RTPM suspend flow and
DP TX flow. When TX is queued during RTPM suspend flow. TX
ring update may be delayed. Add a force TX HP flush when RTPM
is rejected due to TX pending frame. This can help to improve
TX pending frames delay when race condition happens.

In some RX backpressure cases, we see the HW accessing REO
queue descriptors of a deleted peer(after the queue descriptors
are unmapped/freed), this is leading to SMMU faults. There are
cases where the HW is accessing the stale REO queue descriptors
after ~12seconds after the queue descriptors were freed.
In order to avoid the problem, HW team has suggested to defer
unmapping/free of REO Queue descriptors. Add the logic for the
same.

Currently a set of IPA2TCL and WBM2IPA rings is used for
IPA TX data path. Issue is when wlan is configured as
SAP-SAP DBS mode, slow 2G traffic will consume much more
TX resources and thus 5G traffic will have starvation,
which leads to severe degradation of DBS KPI.
Therefore separate IPA2TCL (SW2TCL2) and WBM2IPA (WBM2SW4)
rings are added to support alternative IPA TX pipe for 2G
traffic.

Currently before suspending the device, we are draining
out the TX/RX SRNGs. The HP/TP updates which are done as
part of this will be posted writes(there won't be any link
levelccompletions for write transactions), there are chances
that we might end up updating HP/TP after the device enters
low power mode leading to system crashes.
In order to avoid this scenario, do a dummy read before
device is suspended; this will ensure all pendings writes are
flushed before read returns.
