[PATCH] ieee80211: Renamed ieee80211_hdr to ieee80211_hdr_3addr
tree e9c18b2c8e5ad446a4d213243c2dcf9fd1652a7b parent 4e97ad6ae7084a4f741e94e76c41c68bc7c5a76a author James Ketrenos <jketreno@linux.intel.com> 1124444315 -0500 committer James Ketrenos <jketreno@linux.intel.com> 1127312922 -0500 Renamed ieee80211_hdr to ieee80211_hdr_3addr and modified ieee80211_hdr to just contain the frame_ctrl and duration_id. Changed uses of ieee80211_hdr to ieee80211_hdr_4addr or ieee80211_hdr_3addr based on what was expected for that portion of code. NOTE: This requires changes to ipw2100, ipw2200, hostap, and atmel drivers. Signed-off-by: James Ketrenos <jketreno@linux.intel.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
