From aa571b6275fb60da443c490ebeef021a6897d332 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Mon, 19 Jun 2023 11:24:00 +0200 Subject: [PATCH] net: stmmac: add new switch to struct plat_stmmacenet_data On some platforms, the PCS can be integrated in the MAC so the driver will not see any PCS link activity. Add a switch that allows the platform drivers to let the core code know.
