From d77081cf50489a441739481e096411858c632276 Mon Sep 17 00:00:00 2001 From: Siva Durga Prasad Paladugu Date: Tue, 20 Feb 2018 11:56:19 +0530 Subject: [PATCH] net: zynq_gem: Dont run any phy detection logic for GMII case This patch bypasses phy detection logic for GMII interface and just depend on phy address received from DT. This patch is required as phy detection logic is different for some phys like xilinx phy which can be connected over SGMII and GMII interface. This fixes the issue of ethernet failures when xilinx phy is connected over GMII interface.
