Or if the STA interfaces are promisc for some reason..but no big deal either way. With the old ath9k code, even arps or dhcp requests would be an order-1 SKB, so that is probably what I was seeing. I had a clean overnight run with the ath9k copybreak logic, so that seems to have been the root problem. Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
