802.3cg? 10base-TIS and 10base-TIL are definitely aimed at i= ndustry and automotive.=C2=A0 And look like they=E2=80=99re trying to be al= ternatives to CAN and other networks I=E2=80=99m more familiar with (Device= Net and ControlNet, from Rockwell Automation)

10base-TIL looks very much like the time-token-bus mo= del that ControlNet uses.

=C2=A0 =C2=A0 =C2=A0 =C2=A0 They also have a Gpbs ethernet port:

Ethernet MAC=C2=A0 =C2=A0 2-Port 10/100/1000

I thought al Gbps ethernet is backward compatible to 10 Mbps? At least the = systems I looked at with ethtool clsim that much, e.g.:
