New Revision: 189567
URL: http://svn.freebsd.org/changeset/base/189567
Log:
For IP1001 PHYs, read auto-negotiation advertisement register to
get default next page configuration. While I'm here explicitly set
IP1000PHY_ANAR_CSMA bit. This bit is read-only and always set
by hardware so setting it has no effect but it would clear the
intention. With this change controllers that couldn't establish
1000baseT link should work.
