So far msix vectors allocation assumed it would be 1:1 with
hardware queues. However, there are several reasons why fewer
MSIX vectors may be allocated than hardware queues such as the
platform being out of vectors or adapter limits being less than
cpu count.
This patch reworks the MSIX/EQ relationships with the per-cpu
hardware queues so they can function independently. MSIX vectors
will be equitably split been cpu sockets/cores and then the
per-cpu hardware queues will be mapped to the vectors most
efficient for them.
