Exception: P2P Listen success although in rfkill

[xiangruim]

Hi guys


lkp-tests(https://github.com/01org/lkp-tests) enabled hwsim test 
recently, and currently

we have made most cases pass.


But when we test rfkill_p2p_discovery_p2p_dev case, it always failed.

#test env:

-------------------------------------------------------
it seems that rfkill can not block wpas. Thus, wpas listens to dev[1] 
all the time. Maybe rfkill do not have
the authority to block wpas.


any ideas ?



Thanks
