PCIe only permits 1 device on an endpoint, so some devices ignore the device
part of B:D:F probing. Although ARI likely fixes this, not all platforms
support ARI completely or correctly, so some devices end up showing up 32

Hi Nathan,
There are a ton of ARM boards that need this too. You can find one-off
hacks all through the tree and one of the nice things about this change

Hi Justin,
I can add one either tonight or tomorrow.
Thanks.
If bhyve has its own attachment id, it is trivial
to add a special case on it quickly, too.

Actually, this can also be AMD. A better check would be if the system
