From 873cd42a6358bb3baed71ce53284a9fcce79355d Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 25 Mar 2013 18:29:27 +0100 Subject: [PATCH] mac80211: support secondary channel offset in CSA Add support for the secondary channel offset IE in channel switch announcements. This is necessary for proper handling of CSA on HT access points. For this to work it is also necessary to convert everything here to use chandef structs instead of just channels. The driver updates aren't really correct though. In particular, the TI wl18xx driver update can't possibly be right since it just ignores the new channel width for lack of firmware API.
