ath6kl: Make foreground scan a deterministic one
This makes the device get into scan state as soon as a scan request is received, instead of blocking the scan request till the traffic comes down. It is necessary for the deterministic foreground scan particularly when having multiple vif operating where, if the scan is non- deterministic, scan on one interface will not start as long as there are traffic on the other interface. This change passes 50 msec as foreground scan interval to fix this. Signed-off-by: Vasanthakumar Thiagarajan <vthiagar@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
