In the hardware, you cannot independently enable layer-4 Rx checksums for TCP or UDP, IPv4 or IPv6. It's all or nothing. So that you cannot set the flags to a different state than the hardware, SIOCSIFCAP returns EINVAL when you make an unsupported selection. Try 'ifconfig ixg0 tcp4csum-rx tcp6csum-rx udp4csum-rx udp6csum-tx', that should work. Dave -- David Young dyo...@pobox.com Urbana, IL (217) 721-9981
