This is useful for reconstructing the traffic for network taps
that transmit the RX/TX signals out through two separate interfaces.

The

driver also supports two special link options:
.Bl -tag -width link0
.It Cm link0
Forward only those packets that do
.Cm not
contain valid VLAN tags (ie. packets in vlan 0).
This allows VLAN-tagged packets to be bridged or processed separately.

Forward only those packets that do contain valid VLAN tags.
This is the complement of
