Yes I tested with ath9k wireless card, the same configuration works. I did an interesting test. With ostinato software I generate an ICMP frame without vlan tag. I changed the ethertype in the frame. I tried with the ethertype 0x800 (IP), 0x801, 0x8892 (PROFINET), 0x8100 (dot1q), 0x0600. All frames are sent except when the ethertype is set to 0x8100. It seems the firmware do not accept the ethertype 0x8100. > > > Michał
