The impact is that after a STA disconnects *or* when for any reason a regulatory domain change happens the beacon hint flag is not cleared therefore preventing future beacon hints to be learned. This is important as a regulatory domain change or a restore of regulatory settings would set back the passive scan and no-ibss flags on the channel. This is the right place to do this given that it covers any regulatory domain change. Cc: stable@kernel.org Reviewed-by: Luis R. Rodriguez Signed-off-by: Rajkumar Manoharan Acked-by: Luis R.
