mlx5_eswitch_enable()

However for VFs, vports are initialized before creating their

Similarly while disabling eswitch, first hardware vports are disabled,
followed by destroying their representors.
Here while underlying vports gets destroyed but its respective user

more offload operations.

Instead, its more accurate to do
enable_eswitch switchdev mode:
1. perform FDB tables initialization
2. initialize hw vport
3. create and publish representor for this vport

disable_eswitch switchdev mode:
