From 15eb1069663676243a63a916fe482e751cd56deb Mon Sep 17 00:00:00 2001 From: Joachim Foerster Date: Tue, 25 Oct 2011 22:39:57 +0000 Subject: [PATCH] altera_tse: m88e1111s: Honor device flags regarding PHY interface mode Note: This is kind of guess work. The current code is preserved for all RGMII related modes. It is different for flags=0 (GMII) and flags=5 (SGMII). The last case, SGMII, is successfully tested on Altera's Terasic DE4.
