2018-12-14IB/mlx5: Unify e-switch representors load approach between uplink and VFsMark Bloch
When in switchdev mode and the add function is called by the core level driver, make sure we only register the callbacks, but don't create the mlx5 IB device or initialize anything. With this change all the IB devices in switchdev mode are created only once the load callback is invoked by the e-switch core sub-module. This follows the design paradigm under which the all the Eth representors must be loaded before any of IB reprs is loaded.

This change introduces the ib_device_ops structure that defines all the InfiniBand device operations in one place, so the code will be more readable and clean, unlike today when the ops are mixed with ib_device data members.
