qcacld-3.0: Enhance SAP beacon template updation during DFS CSA
The hosts sends the beacon template to firmware through the
command WMI_BCN_TMPL_CMDID. The firmware sends a TX complete
indication via the WMI_OFFLOAD_BCN_TX_STATUS_EVENT and upon
receiving this host decrements the CSA count.
The hosts waits until the csa count becomes zero and then sends
vdev restart to firmware. There are some issues with this
implementation when 10 beacons with CSA are taking more time
than 1 sec. This is because in STA+SAP case sometime the
WMI_OFFLOAD_BCN_TX_STATUS_EVENT is received after in 200-300ms.
If the host doesn't receive the channel change event, it gets
struck in the channel change.
To avoid this scenario, send the beacon template to the firmware
for every beacon interval without waiting for the beacon TX
complete indication from FW except for the first beacon template
updation. Introduced a new timer (ap_ecsa_timer) to update the
firmware with the beacon template.
