From 6fcc040f02d281c7e9563127358a77ce2bbfe284 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Mon, 11 Oct 2010 21:03:05 +0000 Subject: [PATCH] net: allow FEC driver to use fixed PHY support At least one board using the FEC driver does not have a conventional PHY attached to it, it is directly connected to a somewhat simple ethernet switch (the board is the SnapGear/LITE, and the attached 4-port ethernet switch is a RealTek RTL8305). This switch does not present the usual register interface of a PHY, it presents nothing. So a PHY scan will find nothing - it finds ID's of 0 for each PHY on the attached MII bus. After the FEC driver was changed to use phylib for supporting PHYs it no longer works on this particular board/switch setup. Add code support to use a fixed phy if no PHY is found on the MII bus. This is based on the way the cpmac.c driver solved this same problem. Signed-off-by: Greg Ungerer Signed-off-by: David S. Miller --- Reading git-format-patch failed
