ifmedia(4) says, in part,

           IFM_10_5     10base5, 10Mb/s over 15-wire cables, DB15 connector,
                        also called AUI.  [10base5, AUI, 10AUI]

This is definitely wrong.  10base5 is "thicknet" - the old heavy coax,
500m length limit, whereas AUI is not strictly a media type at all;
it's a host<->transceiver interface that can be used with at least four
different types of transceiver in my experience (10base5, 10base2,
10baseT, and something over fiber that I don't know the proper name of)
and probably more I've never seen.

Now for the purposes of ifmedia(4), AUI should probably count as a
media type, even if it is somewhat of a misnomer.  But the
documentation definitely should not make it sound as though AUI is the
same thing as 10base5!

Also, some of the pins on the AUI connector are unused; "15-wire
cables" is misleading.  Some of my AUI drop cables have as few as nine
pins present on the male (host) connector, and as far as I can tell
they work fine.
