    net/mlx5: E-Switch, Centralize repersentor reg/unreg to eswitch driver · f8e8fa02
    Bodong Wang authored
    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.
