From a831274a1346913c145797ddee6f39e30e061318 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Thu, 16 Jun 2016 12:22:30 -0700 Subject: [PATCH] mlx4_en: Replace ndo_add/del_vxlan_port with ndo_add/del_udp_enc_port This change replaces the network device operations for adding or removing a VXLAN port with operations that are more generically defined to be used for any UDP offload port but provide a type. As such by just adding a line to verify that the offload type is VXLAN we can maintain the same functionality. In addition I updated the socket address family check so that instead of excluding IPv6 we instead abort of type is not IPv4. This makes much more sense as we should only be supporting IPv4 outer addresses on this hardware. Signed-off-by: Alexander Duyck Signed-off-by: David S.
