net/mlx5: Add merged e-switch cap
When merged e-switch is supported, the per-port e-switch is logically merged into one e-switch that spans both physical ports and all the VFs. Under merged eswitch, both the matching on source vport and setting destination vport can have a 2nd attribute which is the vhca id of the eswitch owner. For example: esw0: {match: <src vport=1 owner=0> action: fwd to <dst vport=7, owner=1>} is a flow set on eswitch0 matching on source vport=1 from his eswitch and the action being fwd to dest vport=7 of eswitch1.
