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.
