Author: mav Date: Sat Apr 9 14:50:47 2016 New Revision: 297751 URL: https://svnweb.freebsd.org/changeset/base/297751 Log: Register symbolic port/node names in FC name server. This is cosmetics that simplifies identification of new ports on FC switch. It would be good to use target name from CTL here instead of hostname, but it is not passed here through CAM now.
