New Revision: 190794
URL: http://svn.freebsd.org/changeset/base/190794
Log:
Provide a generic ifmedia set of routines as a fallback. The
DP8390-based cards have no generic way of reporting status of the link
or setting the media type. Some specific versions of these cards do,
however, allow for this, and we already support some of them. Make
the 'ed' experience more uniform by providing "autoselect" as the
meida and status "active" always. This won't affect the chips that
provide more specific details.
