tsnep: Add EtherType RX flow classification support
Received Ethernet frames are assigned to first RX queue per default.
Based on EtherType Ethernet frames can be assigned to other RX queues.
This enables processing of real-time Ethernet protocols on dedicated
RX queues.
Add RX flow classification interface for EtherType based RX queue
assignment.
