How about a sysfs attribute that we can push arbitary data into (up to
a set maximum length) from xend? or maybe a sysfs attribute folder, and
then pass key=value pairs as the data, each of which appears as an entry
in the sysfs folder. Then you just use the interface name (which we
obviously have in the hotplug script) to index into the sysfs tree.

If that sounds like something you might be interested in, i could put
together some code to do it?

Haven't used ebtables in a while, but if no-one else wants to i might
manage to get around to it. No guarantees on this one though.
