[BUG] problems with NICs pass through to OpenBSD guest

[Adam Szewczyk <szewcson@xxxxxxxxx>]

I have QubesOS 4.1.1 with Xen 4.14.5 hypervisor system on which I want to install OpenBSD as a HVM and pass through my NICs to it (Intel Wireless AC-9560 and Realtek 8168 rev 0x15: RTL8168H/8111H). I tested that when installing OpenBSD on actual hardware both NICs seems to working properly. But on hvm ethernet spamming me with: re0: watchdog timeout messages and not working. Wireless causing OpenBSD Panic! first throwing errors like this: iwm0: fw chunk addr 0x404000 len 712 failed to load.

I previously try to report it on OpenBSD mailing list, with my dmesg when only eth passad through attached: https://marc.info/?l=openbsd-bugs&m=166318676430481&w=2

and also on QubesOS issue tracker: https://github.com/QubesOS/qubes-issues/issues/7765

I found also an similar issue with bhyve (re fw on guest not working when passed through the same eth NIC to OpenBSD) on FreeBSD mailing list: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=245392

If You think that error is on the driver side please let me know, I will try to forced it on Open BSD mailing list or report to the fw vendor.
