Just as a review reference, I have found an old attempted
implementation documented here.

That is interesting, but you need to be careful with it.

Top of rack switches are very different beasts to the majority of
switches supported by Linux, which are SOHO. TOR switches have a lot
of firmware running on them doing most of the work. A typical SOHO
switch with a Linux kernel driver has very little firmware, Linux
really is driving it, not just asking it to do things.

Also, TOR switches typically have a binary blob running in userspace,
meaning different information is probably required compared to kernel
driver.

There may be useful information here, but please take it with a big
pinch of salt. And make sure you have the appropriate networking
people involved in any specification work you do.
