Subject: net/mlx5e: Vxlan, move netdev only logic to en_main.c
Patch-mainline: v4.19-rc1
Git-commit: dccea6bf384c853f4a3ca60cb3d729dc41971602
References: bsc#1103990 FATE#326006

Create a direct vxlan API to add and delete vxlan ports from HW.
+void mlx5e_vxlan_add_port(struct mlx5e_priv *priv, u16 port);
+void mlx5e_vxlan_del_port(struct mlx5e_priv *priv, u16 port);

And move vxlan_add/del_work to en_main.c since they are netdev only
logic.
