vrf: make sure skb->data contains ip header to make routing
[ Upstream commit 107e47cc80ec37cb332bd41b22b1c7779e22e018 ]
vrf_process_v4_outbound() and vrf_process_v6_outbound() do routing
using ip/ipv6 addresses, but don't make sure the header is available
in skb->data[] (skb_headlen() is less then header size).
Case:
1) igb driver from intel.
2) Packet size is greater then 255.
3) MPLS forwards to VRF device.
So, patch adds pskb_may_pull() calls in vrf_process_v4/v6_outbound()
functions.
