Can you add to the specification an explanation of why this is needed? In other words, GLDv3 previously (wrongly) assumed that all devices which claimed to support various flavors of hardware checksum offload could so with VLAN-tagged frames. This flag is presumably needed for some potential drivers out there that do hardware checksum, but only for non-vlan-tagged frames (correct?). Do we know of any such drivers offhand? -Seb _______________________________________________ networking-discuss mailing list [email protected]
