There is a bug in bhyve where if the OS assigns the 0x sentinel to
more than one

Does the card have multiple BARs? Can you send us the output of pciconf -lvb
for the card?
There is a bug in bhyve where if the OS assigns the 0x sentinel to more
than one BAR simultaneously it is not compatible with bhyve’s memory model for
the guest.

Yeah, that triggers a barf with error 2:
mmio_rb_lookup: barf ENOENTerror is 2
mr.name is passthru-pci-5
mr.flags is 0
mr.arg2 is 0
mr.base is 18446744073709027328
mr.size is 524288
Assertion failed: (error == 0), function modify_bar_registration, file
/usr/src/usr.sbin/bhyve/pci_emul.c, line 510.

I have noticed that Windows 10 guests fail to boot when attempting to pass
through a network card. I believe I have observed this with both cxgbe
(t580) and mlx5en cards, but only have a cxgbe to test with now. Without
passthrough, the Windows 10 guest boots and operates normally.
