[PATCH 5/6] mac80211: dont use interface indices in drivers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
