> Won't this break the use of A-MSDU in existing 4-addr AP/STA setups? I didn't think it did, but looking closer, that does seem indeed to be the case. Do you remember why you explicitly added code to *not* accept 4-addr frames in non-4addr AP_VLAN, but no other cases? This seems oddly specific. I can change it to accept 4-addr frames in 4-addr cases, but I'll note that it's completely pointless to carry A4 since it will not be used for decapsulation. johannes
