Cannot set frequency on phy device in 3.9.0+ ??

Cannot set frequency on phy device in 3.9.0+ ??

[Ben Greear]

Seems like this used to work.  NIC is ath9k_htc driver, configured with one
VAP and one station.  Both are admin down, but still get EBUSY when trying
to set the frequency.  Seems like this used to work (on ath9k driver, at least).

[root@lec2010-ath9k-1 lanforge]# ifconfig wlan1
