GRE: Add support for GRO/GSO of IPv6 GRE traffic
Since GRE doesn't really care about L3 protocol we can support IPv4 and IPv6 using the same offloads. With that being the case we can add a call to register the offloads for IPv6 as a part of our GRE offload initialization. Signed-off-by: Alexander Duyck <aduyck@mirantis.com> Signed-off-by: David S.
