Unfortunately, I currently do not have the capacity to test this further.

Currently, the host is running stable/15 at 0baae6223a63, and I am using bhyve
with a dynamically created if_bridge in the "wrong" configuration (host IPv[46]
addresses at re0 which becomes part of the bridge), and dynamically created
if_tap devices per VM, which is working well enough for me. I don't have the
feeling that much has changed since I posted the original PR.

The issues might (also) be caused by the fact that re0 is a RTL8125 2.5GbE
Controller vendor=0x10ec device=0x8125, with a barely functioning
net/realtek-re-kmod driver. See the various PRs on that topic.

Once the rge driver is backported from main to stable/15, I'll try that to see
if it improves the situation.
