New Revision: 227842
URL: http://svn.freebsd.org/changeset/base/227842
Log:
For IP1001 PHY, do not set multi-port device(MASTER). Ideally this
bit should not affect link establishment process of auto-negotiation
if manual configuration is not used, which is true in auto-negotiation.
However it seems setting this bit interfere with IP1001 PHY's
down-shifting feature such that establishing a 10/100Mbps link failed
when 1000baseT link is not available during auto-negotiation process.
