Eric Dumazet 354259fa73 net: remove skb->vlan_present
skb->vlan_present seems redundant.

We can instead derive it from this boolean expression:

vlan_present = skb->vlan_proto != 0 || skb->vlan_tci != 0

Add a new union, to access both fields in a single load/store
when possible.

	union {
		u32	vlan_all;
		struct {
		__be16	vlan_proto;
		__u16	vlan_tci;
		};
	};

This allows following patch to remove a conditional test in GRO stack.

Note:
  We move remcsum_offload to keep TC_AT_INGRESS_MASK
  and SKB_MONO_DELIVERY_TIME_MASK unchanged.
