ixgbe: Allocate driver resources per NUMA node
The default policy for the current driver is to do all its memory
allocation on whatever processor is running insmod/modprobe. This
is less than optimal.
This driver's default mode of operation will be to use each node for each
subsequent transmit/receive queue. The most efficient allocation will be
to then have the interrupts bound in such a way as to match up the
interrupt of the queue to the cpu where its memory was allocated.
