A quick follow up on this. According to the ifmedia manpage from NetBSD
(the birthplace of ifmedia):
IFM_HDX Place the device into half-duplex mode. This option on=AD
ly has meaning if the device is normally not half-du=AD
plex. [half-duplex, hdx]
Since classical ethernet is half duplex, it is correct that this is not
a supported option.
