Subject: sky2 auto negotiation PHY errata
From: Stephen Hemminger <shemminger@xxxxxxxxxxxxxxxxxxxx>
This patch does the Marvell errata before auto negotiation
(from drivers/phy/marvell.c). The Yukon II chips have an internal
version of the same PHY, so perhaps this errata is necessary for them
as well.
For test only, but it may fix some of the hangs. It seems to fix
the PHY lockups I saw yesterday on Mac Mini.
