(In reply to Kubilay Kocak from comment #20)

I've been able to reproduce on 14.1-RELEASE

FreeBSD 14.1-RELEASE (GENERIC) releng/14.1-n267679-10e31f0946d8

I have tried various combinations of VFs marked as passthrough or not, and also
with the PF marked for passthrough. In all cases I see the messages as in the
original post shortly after the VM starts.

To reproduce

 1. Configure 2 VFs on each port, mark those on port 1 for passthrough
 2. Host networking uses a VF on port 2
 3. Start a bhyve VM with one of the VFs on port 1 as a passthrough device

I've used nvmupdate to update to the most recent firmware as of 2024-06-07.
System is a minisforum MS-01 with the onboard NICs.
