From aed5a323ec37af3ff230b7cf16045a44136aded3 Mon Sep 17 00:00:00 2001 From: Vincent Jardin Date: Mon, 28 Sep 2026 13:22:46 +0200 Subject: dpaa2-eth: mark DPNIs without a DPMAC as virtual devlink ports A DPNI whose endpoint is not a DPMAC has no physical connector: it may have no endpoint at all, or be connected to another DPNI or to a DPSW port. Until now, such a DPNI was still registered as a physical devlink port with number 0, so userspace saw a physical port that does not exist. Register these DPNIs as virtual devlink ports instead. A virtual port has no phys_port_name, so only the DPNIs that serve a DPMAC at probe time report one, "p", and those names do not collide.
