ath0: device timeout

[Lev Serebryakov]

Hello, Freebsd-wireless.

  Notso-fresh 10.0-CURRENT/i386, ar9820, host-AP mode (WPA2). I've got
this under load:

ath0: stuck beacon; resetting (bmiss count 4)

ar5416PerCalibrationN: NF calibration didn't finish; delaying CCA

  After that "reset" everything works. When NIC is stuck, clients
could see SSID bbut could not associate (and associated clients lost
association).

  Mow I'm building fresh current kernel.
