and the Atheros reference code. The radar detection code needs to know what the current DFS domain is. Since net80211 doesn't currently know this information, it's extracted from the HAL regulatory domain information. The specifics: * add a new ath_dfs API hook, ath_dfs_init_radar_filters(), which updates the radar filters whenever the regulatory domain changes. * add HAL_DFS_DOMAIN which describes the currently configured DFS domain . * add a new HAL internal variable which tracks the currently configured HAL DFS domain. * add a new HAL capability, HAL_CAP_DFS_DMN, which returns the currently configured HAL DFS domain setting. * update the HAL DFS domain setting whenever the channel setting is updated. Since this isn't currently used by any radar code, these should all be no-ops for existing users. Obtained from: Atheros Submitted by: KBC Networks, sibridge Approved by: re (kib, blanket)
