From 614732eaa12dd462c0ab274700bed14f36afea5e Mon Sep 17 00:00:00 2001 From: Thomas Graf Date: Tue, 21 Jul 2015 10:44:06 +0200 Subject: openvswitch: Use regular VXLAN net_device device This gets rid of all OVS specific VXLAN code in the receive and transmit path by using a VXLAN net_device to represent the vport. Only a small shim layer remains which takes care of handling the VXLAN specific OVS Netlink configuration. Unexports vxlan_sock_add(), vxlan_sock_release(), vxlan_xmit_skb() since they are no longer needed. Signed-off-by: Thomas Graf Signed-off-by: Pravin B Shelar Signed-off-by: David S.
