From TFA:

  They have also soft-deprecated the ability to have any layer 3 addresses on member interfaces which makes it behave like a real hardware switch. The net.link.bridge.member_ifaddrs sysctl controls this behavior and it will be removed in FreeBSD 16.0-RELEASE, same as if set to zero.

I'm a little bit uncertain. This means that the bridge may have one or more L3 addresses assigned to it, but the interfaces attached to that bridge may not, right?

If that's right, how does that interact with things like Linux's veth pairs? [0] Can the half of the pair that's not a member of the bridge have an IP address?

[0] I assume something like that exists in FreeBSD-land.
