From f3766c26a5d00189e5c0965c66f01956d15a92d6 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Wed, 13 Jan 2010 10:59:13 +0000 Subject: sfc: Fix conditions for MDIO self-test The MDIO self-test should not be run on boards without an MDIO PHY, such as SFN5122F-R3 and later revisions. It should also not try to address a specific MMD in an MDIO clause 22 PHY. Check the mode_support field to decide which mode to use, if any. Signed-off-by: Ben Hutchings Signed-off-by: David S.
