| |
When parsing an ethtool_rx_flow_spec, users can specify an ethernet flow which could contain matches based on the ethernet header, such as the MAC address, the VLAN tag or the ethertype.
Only the ethtype field is specific to the ether flow, the MAC and vlan fields are processed using the special FLOW_EXT and FLOW_MAC_EXT flags.
