media option generally should be used instead. Actually I think the lists
of media types should be removed from the manual pages of MAC drivers
altogether and users just pointed to the output of `ifconfig -m` instead;
even before r215297 there were several outdated descriptions, technically
it's wrong most of the time as not the MAC drivers support these media
types but actually the PHY drivers do and it generally doesn't make sense
to maintain these lists in every manual page of a driver as the media is
auto-detected.
it mentioned only VT6122. While I'm here remove the mention of
VT3119 which seems to be VIA's internal model name and VT3119
wouldn't be available to end users.
