From 73e4937d489072a26a0077c72c7d50ef2d0bf02b Mon Sep 17 00:00:00 2001 From: Zefir Kurtisi Date: Wed, 3 Apr 2013 18:31:31 +0200 Subject: ath9k: add support for DFS master mode These are the remaining knobs in ath9k to support DFS: * mark AR9280 and AR9580 as DFS tested * synchronize DFS regulatory domain to reg notifyer * set required RX filter flags for radar detection * process radar PHY errors at DFS detector * notify DFS master on radar detection DFS support requires CONFIG_ATH9K_DFS_CERTIFIED to be set.
