net/mlx5: E-switch, Create per vport table based on devlink encap mode

Browse Source 
[ Upstream commit fd745f4c0abe41ebb09d11bf622b054a0f3e7b49 ]

Currently when creating per vport table, create flags are hardcoded.
Devlink encap mode is set based on user input and HW capability.
Create per vport table based on devlink encap mode.
