this should be fixed by https://reviews.freebsd.org/D50477, as long as
you have allow_llz_overlap set to 0 (which is the default, and there's
almost never any reason to change it).
Just built against your patch and it's all working, TYVM.
FreeBSD 14.3-STABLE #2 stable/14-n271551-4e0a5fd7b608-dirty:

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.
