Author: yongari Date: Mon Sep 28 22:18:38 2009 New Revision: 197600 URL: http://svn.freebsd.org/changeset/base/197600 Log: For AR8132 fast ethernet controller, do not report 1000baseT capability to mii(4). Even though AR8132 uses the same model/ revision number of F1 gigabit PHY, the PHY has no ability to establish 1000baseT link. I have no idea why Atheros use the same device/model id for this PHY. With this change atphy(4) does not report 1000baseT media capability and manual 1000baseT configuration is also disabled which is more desirable behavior for 10/100Mbps PHY.
