Late reply. :) I just read if_vlan.c and found that part. My complaint was that readers can't know the intention of (IFCAP_CSUM_IPv4_Tx | IFCAP_CSUM_IPv4_Rx | IFCAP_CSUM_TCPv4_Tx | IFCAP_CSUM_TCPv4_Rx | IFCAP_CSUM_UDPv4_Tx | IFCAP_CSUM_UDPv4_Rx | IFCAP_CSUM_TCPv6_Tx | IFCAP_CSUM_TCPv6_Rx | IFCAP_CSUM_UDPv6_Tx | IFCAP_CSUM_UDPv6_Rx) - is it kind of a selection, or just all ot IFCAP_*?
> I'm only testing with IPv4. Any volunteers for IPv6? I wanted to know that if a) it should work but just not tested, or b) it should not work. In either case comment would be nice IMO. Masao
