Author: adrian Date: Sat Jun 4 04:14:59 2011 New Revision: 222668 URL: http://svn.freebsd.org/changeset/base/222668 Log: A few changes to make radar detection implementable in a hal_dfs/ 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.
