Subject: net/mlx5e: Issue direct lookup on vxlan ports by vport representors
Patch-mainline: v4.19-rc1
Git-commit: a3e673660bc3fca3e9e0cbab871b2fb100e9ed64
References: bsc#1103990 FATE#326006
Remove uplink representor netdevice private structure lookup, and use
mlx5 core handle directly from representor private structure to lookup
vxlan ports.
