Driver's Page Pool allocation code looks at the node local
to the PCIe device to determine where to allocate memory.
In scenarios where the core count per NUMA node is low (< default rings)
it makes sense to exhaust page pool allocations on
Node 0 first and then moving on to allocating page pools
for the remaining rings from Node 1.

With this patch, and the following configuration on the NIC
$ ethtool -L ens1f0np0 combined 16
(core count/node = 12, first 12 rings on node#0, last 4 rings node#1)
and traffic redirected to a ring on node#1 , we see a performance
improvement of ~20%
