Eswitch has two users: IB and ETH. They both register repersentors when mlx5 interface is added, and unregister the repersentors when mlx5 interface is removed. Ideally, each driver should only deal with the entities which are unique to itself. However, current IB and ETH drivers have to perform the following eswitch operations: 1. When registering, specify how many vports to register. This number is the same for both drivers which is the total available vport numbers. 2. When unregistering, specify the number of registered vports to do unregister. Also, unload the repersentors which are already loaded. It's unnecessary for eswitch driver to hands out the control of above operations to individual driver users, as they're not unique to each driver. Instead, such operations should be centralized to eswitch driver. This consolidates eswitch control flow, and simplified IB and ETH driver. This patch doesn't change any functionality.
