Subject: [net-next PATCH 9/9] octeontx2-pf: Add representors for sdp MAC
Date: Tue, 16 Apr 2024 10:36:16 +0530 [thread overview]
Message-ID: <20240416050616.6056-10-gakula@marvell.com> (raw)
In-Reply-To: <20240416050616.6056-1-gakula@marvell.com>
Current silicons support 2 types of MACs, SDP and
RPM MAC. This patch adds representors for SDP MAC
interfaces.
