From 0a9140cff22e405fce1747a2e02d41851c36c55a Mon Sep 17 00:00:00 2001 From: Matt Carlson Date: Fri, 28 Aug 2009 12:27:50 +0000 Subject: [PATCH] tg3: Delay mdio bus init until fw finishes The device firmware uses the MDIO bus during early setup. If the driver modifies the MDIO bus configuration while it is in use by the firmware, any number of bad things can happen. This patch delays MDIO setup until after the firmware posts its magic signature, signifying initialization is complete. Signed-off-by: Matt Carlson Signed-off-by: David S.
