Daisy chained PCIe switches?

[bryanvaz]

Thought of a hilarious idea while shopping for Pi accessories listening to the new USB video of yours: have you ever tried daisy chain your PCIe switches?

I know TI PCIe fabric switches can be daisy chained, but I don't know if any of the other vendors, like Microsemi, baked the functionality into their stack.

Also for laughs someone tried to patent daisy chaining PCIe devices back in 2012; <> (https://patents.google.com/patent/US20130179621A1/en).
