bnxt_en: Enhance TX pri counters

Browse source

The priority packet and byte counters in ethtool -S are returned by
the driver based on the pri2cos mapping.  The assumption is that each
priority is mapped to one and only one hardware CoS queue.  In a
special RoCE configuration, the FW uses combined CoS queue 0 and CoS
queue 1 for the priority mapped to CoS queue 0.  In this special
case, we need to add the CoS queue 0 and CoS queue 1 counters for
the priority packet and byte counters.
