Subject: net/mlx5: Add destination e-switch owner
Patch-mainline: v4.18-rc1
Git-commit: b17f7fc10facca9e1b2b9cef39af0a8179796c14
References: bsc#1103990 FATE#326006

The destination e-switch owner allows a rule in namespace of one e-switch
owner to point to a vport that is natively associated with another
e-switch owner.
