What exactly are you trying to do? This comment here seems to indicate
that there could be some misunderstanding on what mac80211_hwsim is.. It
has nothing to do with a real wireless NIC and is only used to test
mac80211 (and higher layer of the stack) in a software simulated
environment.

Are you using phy0 as the client radio and phy1 as the AP? If not, this
won't work.
