From 8c48b50a1a888ac5511fe856d63f72fb688c6bb4 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Mon, 5 May 2014 11:48:40 +0200 Subject: cfg80211: allow restricting supported dfs regions At the moment, the ath9k/ath10k DFS module only supports detecting ETSI radar patterns. Add a bitmap in the interface combinations, indicating which DFS regions are supported by the detector. If unset, support for all regions is assumed.

In addition advertise max number of supported CSA counters. This is needed when using CSA and eCSA IEs together.
