rtl8192u: don't trample on <linux/ieee80211.h> struct namespace
In order to start reducing the duplicated code/constants/macros in this driver, we need to include <linux/ieee80211.h> to provide the defacto versions. However this driver has structs with the same name as the ones in the main include, so namespace collision prevents us from doing step #1. Since the structs actually differ in their respective fields, we can't simply delete the local ones without impacting the runtime; a conversion to use the global ones can be considered at a later date if desired. Rename the ones here with a vendor specific prefix so that we won't have the namespace collision, and hence can continue on with the cleanup. Automated conversion done with: for i in `find . -name '*.[ch]'` ; do \ sed -i 's/struct ieee80211_hdr/struct rtl_80211_hdr/g' $i ; \ done Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
