Just built against your patch and it's all working, TYVM.

FreeBSD 14.3-STABLE #2 stable/14-n271551-4e0a5fd7b608-dirty: 
Sat May 24 15:16:54 BST 2025

also:

net.link.bridge.allow_llz_overlap: 0
net.link.bridge.member_ifaddrs="0"

my ifconfig_em0 looks like this:

ifconfig_em0="media 1000baseT mediaopt full-duplex up"

bridge0:

ifconfig_bridge0="inet 192.168.1.2/24 addm em0 addm tap0 addm tap1"

speed tests against a freebsd vm installed on tap0 showed no 
significant speed reduction compared to baremetal, which is 
fantastic.

This sort of thing I was looking at back in October last year with 
iperf3, when freebsd guests had sometimes less than half 
the expected throughput.

Next up to test is a -current system with many VMs.
