An iMac G3 and an early PowerMac G4 that I sometimes have access to that do not have 1Gbit/s but have built-in Ethernet show gem0 for the Ethernet device name. (I do not know if all of the 112 that can run FreeBSD would use gem.) But FreeBSD also uses gem for somewhat more modern PowerMac G4s that have 1Gbit/s as well (that I also sometimes have access to). (Some G5's with 1Gbit/s use bge instead of gem.) I guess that puts gem in the "not limited to under 1Gbit/s" category and so not its being mentioned explicitly: implicit STAY. FYI: See https://everymac.com/systems/by_capability/macs-with-ethernet.html which is sub-sorted by speed/"none". It spans more than PowerPC models. Until I found that gem was used with and without 1Gbit/s being available, I had been wondering which Apple PowerPC models would lose Ethernet support: I knew up front that at least the oldest models predated Apple's having 1Gbit/s support. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
