From 352de5573f60af0ab054859931cfb68eecb1832b Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 17 Aug 2010 12:04:34 +0200 Subject: [PATCH] wireless: move documentation books This moves mac80211 documentation into a new 802.11 bookset and also adds a cfg80211 book to the set. All of this is rather incomplete, but it's easier to work with big code moving as a separate patch. Signed-off-by: Johannes Berg Signed-off-by: John W.
