From 1e41e1d2771456274ae2c748ed2cc74524a5863f Mon Sep 17 00:00:00 2001 From: Jussi Kivilinna Date: Sat, 8 Mar 2008 01:23:17 +0200 Subject: rndis_wlan: cleanup, rename and reorder enums and structures Rename enums and structures to ndis_80211_* for greater readability. Also change order so that enumerations are presented first. Signed-off-by: Jussi Kivilinna Signed-off-by: John W.
