This is a retail appliance. They ship with FBSD out of the box
(OPNsense / pfSense), or a Windows OS. I'm hoping we can fix Linux
support for these.
The NICs are embedded on the board, as to the bus they're using it's
beyond me as an end consumer (basically an stb with a console port).

I don't have this controller, but now that we know the steps to
reproduce (enable IP Forwarding and send traffic until buffering
happens) it should be reproducible by anyone.
> 3. Did you test this with kernel.org igc driver code on these kernels? If yes, share the results.
Yes. Kernel panic'd (from the BUG_ON) on 5.10, 5.15, and 6.0.
> 4. How did you connect 6x i226 AICs in the EHL board?
Port 1 and Port 6. Using the ports independently doesn't seem to
reproduce the issue, and is only when traffic is forwarded between
them.
> 5. Did you test with 1x i226 AIC on these kernels in EHL board?
Yes, the problem does not persist. 2 NICs need to be used (on igc),
with traffic passing between them.

Which means (I believe), this should be reproducible on Dual / Quad port NICs using igc as long as they're routing traffic through the same card.
