Mark Bloch b5ca15ad7e IB/mlx5: Add proper representors support
This commit adds full support for IB representor:

1) Representors profile, We add two new profiles:
   nic_rep_profile - This profile will be used to create an IB device that
   represents the PF/UPLINK.
   rep_profile - This profile will be used to create an IB device that
   represents VFs. Each VF will be its own representor.
2) Proper load/unload callbacks, Those are called by the E-Switch when
   moving to/from switchdev mode.
3) Different flow DB handling for when we in switchdev mode.

Mark Bloch b96c9dde17 IB/mlx5: E-Switch, Add rule to forward traffic to vport
In order to forward traffic from representor's SQ to the right virtual
function, every time an SQ is created also add the corresponding flow rule
to the FDB.

Mark Bloch bcf87f1dbb IB/mlx5: Listen to netdev register/unresiter events in switchdev mode
Currently we listen to netdev register/unregister event based on PCI
device. When in switchdev mode PF and representors share the same PCI
device, so in order to pair ib device and netdev in switchdev mode
compare the netdev that triggered the event to that of the representor.

Expose a function that lets you receive the netdev associated what
a given representor.
