[RFC] net: bump the default number of RSS queues

[Jakub Kicinski <jakub.kicinski@netronome.com>]

Some popular NIC vendors are not adhering to
netif_get_num_default_rss_queues() which leads to users being
surprised and filing bugs :)  Bump the number of default RX
queues to something more reasonable for modern machines.

I'm mostly wondering what's the policy on this default?  When
should it be applied?  Why was 8 chosen as the default?  We
can abandon using netif_get_num_default_rss_queues() for the
nfp but I wonder what's the correct course of action here...
Should new drivers use netif_get_num_default_rss_queues() for
example?
