qcacmn: Add new config for BTM offload
Currently, whenever roaming is triggered after a successful roam scan
firmware sends a BTM query to current connected AP when it is 11v
capable. Driver completes roaming with candidates received as part of
BTM request from AP. STA respond to AP with BTM response after
successful initiation of roaming.
Now the requirement is driver could send "BTM query with a preferred
candidate list" after a successful roam scan for some roam scan reasons
like PER, LOW_RSSI, HIGH_RSSI, MAWC, DENSE etc. Preferred candidate list
is obtained as part of roam scan based on firmware bss scoring logic.
New ini "btm_query_bitmask" is introduced to configure the bitmask for
roam scan reasons which is sent to firmware as part of RSO start via
wmi btm config cmd. Fw sends "BTM query with preferred candidate
list" only for those roam scans which are enabled through this bitmask.
New INI: btm_query_bitmask
Min: 0
Max: 0xFFFFFFFF
Default: 0x8
Bitmask : 0x8 (LOW_RSSI) refer enum WMI_ROAM_TRIGGER_REASON_ID.
Add a new parameter "btm_query_bitmask" into wmi btm config
command in order to pass a value of btm_query_bitmask to fw while
BTM offload
