Try "ifconfig em0 hwfeatures" on -current. > neither man page on "em" says anything about check sum offload. Liar. The em driver supports IPv4 receive IP/TCP/UDP checksum offload on all but 82542-based adapters, VLAN tag insertion and stripping, and Jumbo frames on all but 82562V, 82566DC/82566DM and 82573E/82573L/82573V-based adapters. > "em" are advanced cards, do they already do all things out of a box?
