net: fec: add enet-avb IP support
i.MX6SX Enet-AVB support 3 tx queues, 3 rx queues.
For tx queues: ring 0 -> best effort
ring 1 -> Class A
ring 2 -> Class B
For rx queues:
ring 0 -> best effort
ring 1 -> receive VLAN packet with classification match
ring 2 -> receive VLAN packet with classification match
Add enet-avb IP multiqueue support for the driver.
