Merge branch 'vxlan_gso_check'
Joe Stringer says:
====================
Implement ndo_gso_check() for vxlan nics
Most NICs that report NETIF_F_GSO_UDP_TUNNEL support VXLAN, and not other
UDP-based encapsulation protocols where the format and size of the header may
differ. This patch series implements a generic ndo_gso_check() for detecting
VXLAN, then reuses it for these NICs.
Implementation shamelessly stolen from Tom Herbert (with minor fixups):
http://thread.gmane.org/gmane.linux.network/332428/focus=333111
v2: Drop i40e/fm10k patches (code diverged; handling separately).
Refactor common code into vxlan_gso_check() helper.
Minor style fixes.
