If WLAN FW crashes while in suspend mode then kernel tries to
resume the driver and WMA sends resume indication to WLAN FW and
waits for the response from WLAN FW. Since FW is already crashed,
there will not be any response from WLAN FW and wait logic waits
for the timeout before bailing out. This may cause delay in
completing the recovery and may cause other race conditions
becuase of that.
Register for shutdown notification so that call back would be
called during recovery and resume event can be set to make sure
resume thread doesn't just wait for the FW response.

During remove() or shutdown(), driver waits for external thread
to complete but there is no mechanism available today to inform
lower layers that driver is about to go through remove() or
shutdown(). Add mechanism to provide the notification about
remove() or shutdown() so that lower layers can make use of it
and get out of waiting logic and complete the remove() or
shutdown() early without waiting for the timeout to happen.

An assert was observed with the following traceback:
qdf_mc_timer_stop+0x90/0x140 [wlan]
hdd_wmm_disable_inactivity_timer+0x54/0xd0 [wlan]
hdd_wmm_delts+0x168/0x240 [wlan]
iw_del_tspec+0x94/0xf0 [wlan]
In hdd_wmm_disable_inactivity_timer() there is sufficient guard logic
to only act upon a valid timer:
if (pQosContext->is_inactivity_timer_running == true) {
So it is apparent that this flag was set to true. However in this
specific use case the logs show that in the addTS path the timer was
not started and the flag was not explicitly set. So the only
explanation is that the flag was set via some other mechanism.
There are two places where a pQosContext is allocated and initialized.
In hdd_wmm_acquire_access() the implicit qos case is handled, and in
that function there is an explicit assignment:
pQosContext->is_inactivity_timer_running = false;
In hdd_wmm_addts() the explicit qos case is handled, and in that
function there is not an explicit assignment.
Note the memory is allocated by:
pQosContext = kmalloc(sizeof(*pQosContext), GFP_KERNEL);
And there is not an explicit clearing of the memory. Hence in the case
of an explicit addTS the is_inactivity_timer_running flag will have a
garbage value. So in the case at handle this garbage value must have
been equal to true.
Fix this by explicitly setting is_inactivity_timer_running in the
explicit qos case.

Proapagation from qcacld-2.0 to qcacld-3.0.
Currently pktstats are stored in static allocated memory. This

in static memory array because of which incomplete data goes when
queried using hal_proxy_daemon.
Fix this by maintaining the pktstats in link list. When the
request comes from hal_proxy_daemon, complete data is sent
to it from this link list

In USB solution, hif_usb_remove costs ~25s after card unplugged.
Test step is simple, do p2p listen, then unplug card. Sme session
close costs 15s. When do p2p listen, scan will be issued to fw, but this
cmd is stuck in smeScanCmdActiveList which cause session close cmd
eSmeCommandDelStaSession blocked and the timeout is 15s.
This solution is that remove scan from smeScanCmdActiveList
if scan cmd pending in active list when close session.

qcacld-2.0 to qcacld-3.0 propagation
In a SNS case, driver receives ASSOC Req during the SAP
Stopping. The SAP stopping will issue WMI_VDEV_DOWN_CMDID
WMI command to firmware. And ASSOC req frame processing
will issue a WMI_PEER_CREATE_CMDID WMI command to firmware.
Then the firmware crash happens because firmware can't find
the necessary BSS information to create the peer. Firmware
doesn't support peer create after BSS down.
The fix is to ignore the ASSOC Req frame while the deleting
BSS is ongoing.

qcacld-2.0 to qcacld-3.0 propagation
In case of P2P device and P2P GO using seperated
interface, if P2P Device interface listen (remain on
channel) with long duration is active, P2P GO interface
vdev start command will be timeout.
In shared interface case, driver will cancel existing
P2P listen during interface type changing from P2P device
to P2P GO in __wlan_hdd_cfg80211_change_iface. There
is no such issue.
This fix is to extend the canceling logic just before P2P GO
starting to avoid the vdev start timeout in first case.
