Merge branch 'dissect-ptp-l2-packet-header'

Eran Ben Elisha says:

====================
Dissect PTP L2 packet header

This series adds support for dissecting PTP L2 packet
header (EtherType 0x88F7).

For packet header dissecting, skb->protocol is needed. Add protocol
parsing operation to vlan ops, to guarantee skb->protocol is set,
as EtherType 0x88F7 occasionally follows a vlan header.
