When sending packet from representor, the vport ID in transport domain
is E-Switch manager vport ID since representor shares resources of
eswitch manager. To match packet sent by representor, pattern has to be
vport_id==<esw-mgr-id> && txq==<sqn>
On BlueField, eswitch manager ID is 0xfffe. 0 on other NIC.
