We're trying a different approach to make the work more transparent and enable receiving feedback earlier during development. This patch will be updated with bug fixes and missing features. There is also a pull request on Github if you'd like to see commits history: https://github.com/freebsd/freebsd-src/pull/1573

Wasn't there supposed to be support for VLAN anti-spoof and resource limits added to this? Though, the description does say that this is a work in progress.

Yeah, there are still some things missing. I just added your patch with resources limits. I need to double check on the VLAN anti-spoof.
