I'd want a big hunk of steel that would stay where I put it, and I'= m okay if it
also dissipates some heat.


Five years ago, I built a dozen OrangePIZero's with two extra USB ether= nets
in a 3D printed box.=C2=A0 So, a total of three ethernets.=C2=A0 I meant to= build a
hundred of them.=C2=A0 The most complex topology one can build with two eth= ernets
is a circle.=C2=A0 Three ethernets opens one up to all sorts of trees, etc.=
This was for RFC8994 testing.=C2=A0 =C2=A0So I continue to look for ~$20 bo= xes that
could easily do more than two ethernets.=C2=A0 I don't need high speed,= but it's
nice to have. I do need auto-MDX, which GbE PHYs all offer.=C2=A0 One reaso= n I
didn't proceed was that I still haven't gotten beyond what I can do= in
VMs. (i.e. my software is not ready)
At the time, OpenWRT did not do well with the various switch-port extension= s
that got one 4-5 ethernets: they were will custom jobs, but now they are mostly all do DSA, so a 12-port Zyxel would seem to satisfy my needs.
