From f698d856f65c3fea091cc303a135967965c5b880 Mon Sep 17 00:00:00 2001 From: Jasper Bryant-Greene Date: Sun, 3 Aug 2008 12:04:37 +1200 Subject: replace net_device arguments with ieee80211_{local,sub_if_data} as appropriate This patch replaces net_device arguments to mac80211 internal functions with ieee80211_{local,sub_if_data} as appropriate. It also does the same for many 802.11s mesh functions, and changes the mesh path table to be indexed on sub_if_data rather than net_device. If the mesh part needs to be a separate patch let me know, but since mesh uses a lot of mac80211 functions which were being converted anyway, the changes go hand-in-hand somewhat. This patch probably does not convert all the functions which could be converted, but it is a large chunk and followup patches will be provided.
