net: Add vxlan_gso_check() helper 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 differs. This patch implements a generic ndo_gso_check() for VXLAN which will only advertise GSO support when the skb looks like it contains VXLAN (or no UDP tunnelling at all). Implementation shamelessly stolen from Tom Herbert: http://thread.gmane.org/gmane.linux.network/332428/focus=333111 Signed-off-by: Joe Stringer <joestringer@nicira.com> Signed-off-by: David S.
