[arbel] Synchronise changes with the Hermon driver
Backport some changes from the Hermon driver to the Arbel driver. Specifically: o Rename reserved_lkey to lkey o Add arbel_rate() to calculate transmission rates o Structure code to allow for addition of RC queue pairs Signed-off-by: Michael Brown <mcb30@ipxe.org>
