Merge branch 'net-vlan-claim-one-bit-from-sk_buff'

Eric Dumazet says:

====================
net: vlan: claim one bit from sk_buff

First patch claims skb->vlan_present.
This means some bpf changes, eg for sparc32 that I could not test.

Second patch removes one conditional test in gro_list_prepare().
