WDS uses layer 2 multicast (not layer 3) which makes it unroutable.

I am not mentioning IPv4 multicast addresses, which you are right are mapped to
ethernet MAC starting with 01-00-5E.
01:40:96:ff:ff:c0 is well-known ETHERNET multicast address for iapp protocol.
Regarding inter-subnet WLCCP i suggest to read patent related to creation of
WLCCP protocol:
http://www.google.com/patents/US7706345, which clearly states that there is
specification on how to pass inter-subnet WLCCP traffic
