Going back to your original commit 16917b87a "net-next: Add
netif_get_num_default_rss_queues" I am still not clear why we want

1. why we want a common default to all MQ devices?

2. why this default has to be hard coded and not derived e.g from the
number of cores or alike attribute of the system?

Can you please elaborate?

Or.
