module.
* If sc->sc_dodfs is set to 1 by the ath_dfs_radar_enable(),
set the relevant rx filter bit to begin receiving radar PHY
errors. The HAL code already knows how to set the relevant
error mask register to enable radar events.
* Add a missing call to ath_dfs_radar_enable() after ath_hal_reset()
* change ath_dfs_process_phyerr() to take a const char *buf for now,
rather than a descriptor. This way it can get access to the packet
buffer contents.
