Hi Tony,
There is work currently being done for 802.1ad. Active discussions are
on the dev list.
Userspace support:
http://openvswitch.org/pipermail/dev/2016-July/074337.html
http://openvswitch.org/pipermail/dev/2016-August/077136.html
Dataplane tests:
http://openvswitch.org/pipermail/dev/2016-August/077014.html
There is also kernel support in the works, but no recent series has been
posted. It needs changes to support the 802.1ad feature flag referenced
in the threads above. But if there is interest I can post a RFC version
to the dev list.
Eric.

They have resumed again and are based on Thomas F Herbert's original
work. See links above.

Yup. See the dev list and links above.
Help testing and reviewing the existing patch sets would be fantastic.

Join the discussions, test, review, etc. The more eyes the better.

That's the goal!
>Any help appreciated.
