Subject: [net-next v4 12/14] octeontx2-af: cn10k: Add RPM LMAC pause frame support
Date:   Sat, 6 Feb 2021 04:20:11 +0530

From: Rakesh Babu <rsaladi2@marvell.com>

Flow control configuration is different for CGX(Octeontx2)
and RPM(CN10K) functional blocks. This patch adds the necessary
changes for RPM to support 802.3 pause frames configuration on
cn10k platforms.
