Author: wblock (doc committer) Date: Thu Jan 3 21:35:25 2013 New Revision: 245009 URL: http://svnweb.freebsd.org/changeset/base/245009 Log: MFC r242697,r242704: r242697: Add devd.conf(5) and devd(8) to SEE ALSO xrefs. Give users a pointer to seemingly mysterious actions that are not done by ifconfig itself, but by devd triggering on events caused by ifconfig. r242704: Remove fifteen-year-old notes on media selection (suggested by simon@). Add commas after "e.g." and "i.e.".
