 This means a couple things:

OR it would be turned around by the bridge. Bridges have MAC addresses. In particular, if there is a management entity in a bridge (e.g. the one you need for OA&M) then it would be a reasonable TEST target

 We could define TEST as an ethertype

It's been done, 9000h

and hope that all the bridge vendors
implement MAC Clients to handle it... but I doubt this would happen.

PS: I just noticed an earlier response from Tony Jeffree also mentioning
bridges, but I'm gonna send this one anyway.
