Subject: [PATCH v4 net-next 3/8] sfc: enumerate mports in ef100
Date: Tue, 31 Jan 2023 14:58:17 +0000 [thread overview]
Message-ID: <20230131145822.36208-4-alejandro.lucero-palau@amd.com> (raw)
In-Reply-To: <20230131145822.36208-1-alejandro.lucero-palau@amd.com>
From: Alejandro Lucero <alejandro.lucero-palau@amd.com>
MAE ports (mports) are the ports on the EF100 embedded switch such
as networking PCIe functions, the physical port, and potentially
others.
