mac80211: dont use interface indices in drivers
This patch gets rid of the if_id stuff where possible in favour of a new per-virtual-interface structure "struct ieee80211_vif". This structure is located at the end of the per-interface structure and contains a variable length driver-use data area. This has two advantages: * removes the need to look up interfaces by if_id, this is better for working with network namespaces and performance * allows drivers to store and retrieve per-interface data without having to allocate own lists/hash tables Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
