description:
If the driver only supports one media type, and ifmedia_ioctl() is called to
select the current medium, (and it is not autoselect), assume no change and
do not try to select the medium. Fixes 'ifconfig le0 medium 10base5' on sparc2
without requiring a 'do nothing' mediachange callback.
