Ah, interesting. This is the third example of this in about a
month. Take a look at the Realtek and TI work in this area.

So, i will ask the same questions i put to Realtek and TI. Does Linux
know about the switch in any way? Can it manage the switch, other than
SNMP, HTTP from user space? Does it know about the state of the ports,
etc?

If you say this is just a colocated management switch, which Linux is
not managing in any way, that is O.K. If you have Linux involved in
some way, please join the discussion with TI about adding a new model
for semi-autonomous switches.
