[net-next 13/14] octeontx2-af: cn10k: Add RPM Rx/Tx stats support

From: Geetha sowjanya
Date: Sat Jan 30 2021 - 12:08:48 EST

From: Hariprasad Kelam <hkelam@xxxxxxxxxxx>

RPM supports below list of counters as an extension to existing counters
* class based flow control pause frames
* vlan/jabber/fragmented packets
* fcs/alignment/oversized error packets

This patch adds support to display supported RPM counters via debugfs
and define new mbox rpm_stats to read all support counters.
