    mac80211: dont use interface indices in drivers · 32bfd35d
    Johannes Berg authored
    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
