rt2x00: trim skb_frame_desc to 32 bytes
Remove frame_type from skb_frame_desc and pass it as argument to rt2x00debug_dump_frame(). Change data_len and desc_len to unsigned short to save another 4 bytes in skb_frame_desc. Note that this was the only location where the data_len and desc_len was not yet treated as unsigned short. This trim is required to help mac80211 with adding the TX control and TX status informtation into the skb->cb structure. When that happens, drivers will have approximately 40 bytes left to use freely. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
