What happens if I force my card to eg 100 half duplex? Then the
switch can't detect a link failure and has no reason to restart
nway. I'd say our driver has to initiate an autonegotiation session,
advertising only the bit(s) wanted by the user, if the media setting
is changed.
(Strictly speaking, nway is a property which is orthogonal to
the media setting - it is not clean to associate it with IFM_AUTO.)
