[PATCH net 0/5] Implement ndo_gso_check() for vxlan nics

From: Joe Stringer
Date: Tue Nov 04 2014 - 17:03:09 EST


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 ndo_gso_check() for these NICs,
restricting the GSO handling to something that looks and smells like VXLAN.

Implementation shamelessly stolen from Tom Herbert (with minor fixups):

If there are particular differences for your driver on actual support, I'd like
to hear about it. I adjusted the i40e driver to report support with tunnel
headers of up to 64 octets, perhaps there are other specifics that I've missed.

be2net: Implement ndo_gso_check()
i40e: Implement ndo_gso_check()
fm10k: Implement ndo_gso_check()
