If you look at the patch, it removes the sequence numbers for non-TID frames, and puts them back into rt2x00 because I thought rt2x00 was the only driver that needed software sequence numbering. It looks like rtl8187 and zd1211 might need that too, so we need to copy the rt2x00 code that I put into that particular patch to those drivers. johannes
