Subject: [net-next v4 13/14] octeontx2-af: cn10k: Add RPM Rx/Tx stats support
Date:   Sat, 6 Feb 2021 04:20:12 +0530

From: Hariprasad Kelam <hkelam@marvell.com>

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.
