Detailed Description

RTE_FLOW_ITEM_TYPE_ETH

Matches an Ethernet header.

Inside hdr field, the sub-field ether_type stands either for EtherType or TPID, depending on whether the item is followed by a VLAN item or not. If two VLAN items follow, the sub-field refers to the outer one, which, in turn, contains the inner TPID in the similar header field. The innermost VLAN item contains a layer-3 EtherType. All of that follows the order seen on the wire.

If the field in question contains a TPID value, only tagged packets with the specified TPID will match the pattern. Alternatively, it's possible to match any type of tagged packets by means of the field has_vlan rather than use the EtherType/TPID field. Also, it's possible to leave the two fields unused. If this is the case, both tagged and untagged packets will match the pattern.
