[PATCH 123/641] Staging: rtl8187se: rename struct ieee80211_hdr to struct ieee80211_hdr_4addr
Greg Kroah-Hartman
gregkh at suse.de
Tue Sep 15 19:05:54 UTC 2009
From: Bartlomiej Zolnierkiewicz <bzolnier at gmail.com>
ieee80211_hdr name is too generic so use ieee80211_hdr_4addr one instead
(which matches the naming used by rtl8192su driver).
