I realize now that I wrote a reply to only Mike and not the whole misc earlier.
Anyway. The server is running several functions, and it's not popular to do maintenance on it. I went ahead and rebooted it anyway since this is important ;-) I booted the OpenBSD 6.3 install media natively on the hardware. It found all six NICs that I have installed. There are two Broadcom on the mainboard and four on the Intel card. Broadcoms were found as bge and Intel as em. They all seemed to work. I had an extra bge card lying around. I installed it in the server and did PCI passthrough with it as well as the Intel in FreeBSD/bhyve. I get the same result in OpenBSD: bge0 at pci0 dev 5 function 0 "Broadcom BCM5720" rev 0x00, BCM5720 A0 (0x5720000), APE firmware NCSI 1.4.12.0: couldn't map interrupt Conclusion: The problem has to do with the fact that bhyve is between the hardware and OpenBSD. Any ideas?
