SVN rev 184190 on 2008-10-23 00:54:07Z by yongari
MFC r183966:
Some 88E1149 PHY's page select is initialized to point to other
bank instead of copper/fiber bank which in turn resulted in
wrong registers were accessed during PHY operation. It is
believed that page 0 should be used for copper PHY so reinitialize
E1000_EADR to select default copper PHY.
This fixes link establishment issue of nfe(4) on Sun Fire X4140.
OpenBSD also has similimar patch but they just reset the E1000_EADR
register to page 0. However some Marvell PHYs((88E3082, 88E1000)
don't have the extended address register and the meaning of the
register is quite different for each PHY model. So selecting copper
PHY is limited to 88E1149 PHY which seems to be the only one that
exhibits link establishment problem. If parent device know the type
of PHY(either copper or fiber) that information should be notified
to PHY driver but there is no good way to pass this information yet.
