From 1d10bd167667655362a7e2b407a96aad5979bfca Mon Sep 17 00:00:00 2001 From: John Hurley Date: Wed, 7 Nov 2018 18:32:48 +0000 Subject: [PATCH] net: add netif_is_geneve() Add a helper function to determine if the type of a netdev is geneve based on its rtnl_link_ops. This allows drivers that may wish to offload tunnels to check the underlying type of the device. A recent patch added a similar helper to vxlan.h Signed-off-by: John Hurley Reviewed-by: Jakub Kicinski Signed-off-by: David S.
