[PATCH v2 27/32] common/cnxk: configure PFC on SPB aura

[Nithin Dabilpuram]

From: Sunil Kumar Kori <sk...@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.
