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

Fix is to use the appropriate memory size for tx_hw_desc_history

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.

CVE-2020-26145
Broadcast and multicast frames should never be fragmented. Several devices
process broadcasted fragments as normal unfragmented frames. Moreover, some
devices accept plaintext fragmented broadcast or multicast frames in
protected Wi-Fi networks. An adversary can abuse this to inject packets
by encapsulating them in a fragmented plaintext broadcast frame. Even
unicast packets can be encapsulated in broadcast Wi-Fi frames and hence
be injected.

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.

mac_id is used to index into the history array. The array is
of size 1 and OOB access would happen when ring_num which
is the mac_id, passed in is 1.
Fix is to pass the pdev->lmac_id instead to
