This patch enables the load balancing capability of firmware
and hardware to spray traffic into different cpus through
separate rx msix interrupts.
The feature is being enabled for NX3031, NX2031 (old) will be
enabled later. This depends on msi-x and compatibility with
msi and legacy is maintained by enabling single rx ring.

o remove max_ prefix from ring sizes, since they don't really
represent max possible sizes.
o cleanup naming of rx ring types (normal, jumbo, lro).
o simplify logic to choose rx ring size, gig ports get half
rx ring of 10 gig ports.

Remove flash size check which made sense only for ancient
boards with 1MB flash. The check is based on values read
from specific locations and fails with firmware size changes.
This prevents driver from getting right mac addresses.
