Hi,

i'm working on a part of the 802.1ah standard, namely the mac-in-mac
encapsulation. I'll see if i can push it out soon.

Note that that only gets you a quarter of the job done since you need
PBB bridge behaviour as well, which is somewhat more complex to do than
the encapsulation. It will probably require some extensions to the
kernel<>userspace STP interface.

802.1X is supported by hostapd. (http://hostap.epitest.fi) with the
"wired" driver. There's nothing needed from kernel side for this.

802.1ag you can maybe implement in userspace, i don't know the spec to
tell.
