hdd_for_each_adapter_dev_held_safe API takes dev_hold and
during cleanup of interface, dev is unregistered. So later
when dev_put is called, it results in illegal access to
unregistered dev.
Fix this issue by releasing dev_hold before interface cleanup.

Tx register write is permitted after hif bus resume during runtime pm
resume, don't wait WMI_WOW_WAKEUP_HOST_EVENTID.
In F/W, there is an race condition when exit from WOW, both
WAL_TX_TID_TQM and WAL_TX_TID_TRANSITION_TO_TQM_ONGOING are not set yet,
data frame is received from host, assert will hapen.
To fix it, host tx register write shouldn't be permitted to update hp
until receive the WMI_WOW_WAKEUP_HOST_EVENTID.

Add ini 'cfg_tx_iot_aggr', it gives an option to
configure Tx aggregation size in no. of MPDUs/MSDUs
for specified OUI. This can be useful for IOT issues.
Format of the configuration:
cfg_tx_iot_aggr=<OUI-1>,<MSDU-1>,<MPDU-1>,<OUI-2>,<MSDU-2>,<MPDU-2>...
MSDU/MPDU means the max tx aggregation size in no. of MSDUs/MPDUs,
0 means not specified.
For example:
cfg_tx_iot_aggr=112233,2,0,445566,3,32,778899,0,64
If vendor OUI-1("\x11\x22\x33") is found in assoc resp,
set tx amsdu size to 2;
If vendor OUI-2("\x44\x55\x66") is found in assoc resp,
set tx amsdu size to 3, set tx ampdu size to 32;
If vendor OUI-3("\x77\x88\x99") is found in assoc resp,
set tx ampdu size to 64.

Initially, Host updates the AKM only after the EAPOL
handshake. Due to this, Enterprise auth is not detected
for initial connection.
So, add new API which gets the AKM from vdev and convert
it to WMI enum and send it in peer assoc command to firmware
during initial connection. In Firmware, this will help to
detect Enterprise auth as part of connection and prioritize
the WLAN connection over BT traffic accordingly.

The below described scenario can lead to a deadlock
between wlan_hdd_del_virtual_intf and the work handler
to update netdev features.
- netdev features update work is scheduled and takes the
vdev ops DSC lock.
- before the work is able to take the rtnl lock, a delete
interface is called from kernel with rtnl lock held
- wlan_hdd_del_virtual_intf waits indefinitely for all the
ops to be completed on this vdev.
- Now netdev feature update work is waiting for rtnl lock
with vdev ops DSC held, and wlan_hdd_del_virtual_intf is
waiting for vdev ops DSC with rtnl lock held.
In order to fix the above deadlock scenario, set a delete in
progress flag in wlan_hdd_del_virtual_intf and use rtnl_trylock
in the netdev features update work, only if the delete in
progress flag is not set. Using rtnl_trylock with a few equally
time spaced attempts to acquire rtnl lock will make sure the
features update is done it the work is unable to acquire the
rtnl lock due to any other netdev operation (apart from interface
deletion).

The sequence of roam states info print depends on
the sequence of Tlvs coming via WMI_ROAM_STATS_EVENTID
event.
FW does not send roam trigger, roam scan and btm rsp
info to HOST in case of new host and old FW combo.
This results in 11v info print miss in kmsg log.
Fix is to print tlvs info in a proper sequence.

Add validation for STA CSA channel change notify event:
1. acquire the wdev->mtx lock before invoke kernel API -
cfg80211_ch_switch_notify. Kernel will access wdev->current_bss
in the API, it maybe changed in other thread.
2. if the bssid is not connected in vdev, don't invoke kernel API -
cfg80211_ch_switch_notify since wdev->current_bss maybe unlinked from
kernel bss list. cfg80211_ch_switch_notify make assumption
current_bss existing on the bss list.
