From 33787fc4bea0347d78a211d1f38289b73d9ec1a6 Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Mon, 11 Nov 2013 20:34:54 +0200 Subject: mac80211: move csa_chandef to sdata There is no reason why we should have only one channel switch announcement at a time for a single phy. When support for channel switch with multiple contexts and multiple vifs per context is implemented, we will need the chandef data for each vif. Move the csa_chandef structure to sdata to prepare for this.
