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:
kconfig: x86_64-rhel-7.2
compiler: gcc-6
rootfs: debian-x86_64-2016-08-31.cgz
kernel: vmlinuz-4.13.0-rc1-00096-g54a7d50

- CONFIG_MAC80211=m

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 ?
