Not only that, but all correctly implemented GigE
devices will fall back not just to 100 but also to 10 Mb/s. That's part of standards
conformance, and from what I can tell even low cost devices like D-Link or Netgear do
this. Yes, including half duplex mode.
In ~1997 my ISP provided a Terajet 410 and that was very fussy about
what it would talk to; I couldn't get it to talk to my PC or laptop at
the time at 100MB/s ... in the end I just connected to it via a small
DEChub at 10MB/s and it worked perfectly.
Right now my motherboard has a 2.5GB/s ethernet port and it needed
poking with ethtool to autonegotiate at 1Gbps with a TP-LINK TL-SG116.
No idea why yet and I probably won't know until I have a chance to power
both off and prod.
So your statement about "correctly implemented GigE devices" is
technically correct (the best kind of 'correct'!) but I have yet to be
convinced that it's not describing the null set :-)
