> When VSI increases the number of queues dynamically, the scheduler just
> needs to add the new required nodes rather than re-adjusting with
> previously allocated number of nodes. Readjusting didn't provide enough
> parents to add the upper layer nodes also can't place lan and rdma subtrees
> separately.
> 
> In decrese case, keep the VSI configuration with max number of queues
> always. This will leave some extra nodes in the tree but no harm done.
