From: Sunil Kumar Kori <skori at marvell.com>
A RQ can be configured with lpb_aura and spb_aura at the same time
and both can contribute to generate aura based back pressure from
NIX to RPM.
But currently PFC configuration are applied on lpb_aura only and
spb_aura does not contribute to create back pressure.
Patch adds support for the same.
