Subject: [PATCH v2 net-next 0/4]: Allow head adjustment in XDP prog

This series adds a helper to allow head adjusting in XDP prog.  mlx4
driver has been modified to support this feature.  An example is written
to encapsulate a packet with an IPv4/v6 header and then XDP_TX it
out.

v2:
1. Make a variable name change in bpf_xdp_adjust_head() in patch 1
2. Ensure no less than ETH_HLEN data in bpf_xdp_adjust_head() in patch 1
3. Some clarifications in commit log messages of patch 2 and 3

Thanks,
--Martin
