[PATCH net-next v3 07/10] net: fec: fec_enet_rx_queue(): replace manual VLAN header calculation with skb_vlan_eth_hdr()

[Marc Kleine-Budde]

For better readability and maintainability, use the provided helper function
skb_vlan_eth_hdr() to replace manual the VLAN header calculation, and change
the type of vlan_header to struct vlan_ethhdr to take into account that the
Ethernet header plus VLAN header is returned.
