> Properly reconfigure VF VSIs after VF request ADq.
> Created new function to update queue mapping and queue pairs per TC with
> AQ update VSI. This sets proper RSS size on NIC.
> VFs num_queue_pairs should not be changed during setup of queue maps.
> Previously, VF main VSI in ADq had configured too many queues and had
> wrong RSS size, which lead to packets not being consumed and drops in
> connectivity.
> 
> Fixes: bc6d33c8d93f ("i40e: Fix the number of queues available to be mapped
> for use")
