Author: yongari Date: Mon Apr 23 03:38:40 2012 New Revision: 234593 URL: http://svn.freebsd.org/changeset/base/234593 Log: MFC r234121: Back out r228476. r228476 fixed superfluous link UP/DOWN messages but broke IPMI access during boot. It's not clear why r228476 breaks IPMI and should be revisited.
