Following those exact same commands but with FreeBSD-10.0-RELEASE, FreeBSD-10.1-RELEASE, or FreeBSD-11.0-CURRENT, all the commands are accepted without any errors or warnings, however there is no bandwidth limiting and no delay inserted when passing traffic across the bridge. It appears that dummynet is broken, at least for bridges, since at least 10.0-RELEASE. Could this be fixed?
