qcacld-2.0 to qcacld-3.0 propagation
While suspending threads suspend complete event is set before
resume wait event is initialized.
In case resume is followed by suspend there might arise a condition
where resume wait event is set even before its initialization.
Thus after initializing the wait event thread will keep on waiting
on the event and thus get stuck.
To avoid this initialize the thread resume wait event before
setting the suspend event.

Provide support for STA+SAP DFS concurrency feature
Here is the brief description on the changes,
1) if STA came up first on DFS channel and SAP is coming up second
then as per concurrency rule SAP can't come up on DFS channel,
it can come up on 5G-non-dfs or 2G band.
2) if SAP came up first on DFS channel and STA is coming up second
then as per concurrency rule SAP has to move to non-dfs channel
by using channel switch announcement IE. Once SAP moves to
non-dfs channel then and then STA can continue on connection.
3) if there is any STA connection alive then SAP/GO's PCL shouldn't
contain any DFS channel in the list.

only in wlan_hdd_cfg80211.h/c as this is the cfg80211 interface

Fix the reason code used during Nss update request. If
there is MCC upgrade or DBS downgrade, the hw mode change
request internally send the Nss update request. But, the
current implementation uses the same fixed reason code
during Nss update request and due to this on receiving the
hw mode change response, the expected callback function is
not getting invoked. Fix this by passing the right reason
code during Nss update request.

Fix the incorrect value of receive spatial streams added for use
in operating mode field. The Operating Mode field is present in
the Operating Mode Notification frame and Operating Mode
Notification element. These are used to notify STAs that the
transmitting STA is changing its operating channel width, the
maximum number of spatial streams it can receive, or both.
As per the 802.11ac spec:
- If the Rx NSS Type subfield is 0, indicates the maximum number
of spatial streams that the STA can receive.
- If the Rx NSS Type subfield is 1, indicates the maximum number of
spatial streams that the STA can receive as a beamformee in an SU
PPDU using a beamforming steering matrix derived from a VHT
Compressed Beamforming report with Feedback Type subfield
indicating MU in the corresponding VHT Compressed Beamforming
frame sent by the STA.
Set to 0 for Nss = 1
Set to 1 for Nss = 2

Set to 7 for Nss = 8

Set the hw mode, if needed, during channel switch in STA and
P2P-CLI scenario. The STA/P2P-CLI on receiving the channel change
event may need to do a hw mode change to get the best out of the
hw capabilities.
e.g.1, In a STA+SAP concurrency, the STA and SAP are doing SCC on
channel 6. When the STA interface receives a channel event for
channel 36, it is better the driver moves to a DBS scenario.
e.g.2, In a STA+SAP concurrency, the STA is on channel 6 and the
SAP is on channel 36. When the STA interface receives a channel
event for channel 36, it is better the driver moves from a DBS
scenario to a SCC scenario.
For MCC upgrade, the following steps are taken
1. Opportunistic timer is started
2. vdev restart is initiated on the new channel
3. PM will check if MCC upgrade can be done on timer expiry
For DBS downgrade, the following steps are taken
1. PM will initiate HW mode change to DBS right away
2. vdev restart is initiated on the new channel

qcacld-2.0 to qcacld-3.0 propagation
When self recovery initiated, CRASH_INJECT command is sent to
firmware. If firmware crash doesn't reach the host in time then
RuntimePM may kick in and try to suspend the PCIe link. At this
time, firmware might already been crashed just that host missed
the interrupt. Add the logic to prevent the Runtime suspend when
initiating the recovery so that host driver doesn't attempt the
suspend which may not go through and cause stability issues.
