hmm what means not available?

adhoc mode does not need 6mbps, "our" routing protocols also do not need a
specifiy multi-cast rate,.

but having it on 1mbit, means protocol traffic needs more airtime. (which
especially in large networks (with more protocol traffic) gets an issue)

and additionally 1mbit mcast-rate means that the link-quality detection
which is based on packetloss or protocol traffic, will test the link with
an quite "unrealistic" rate, leading to detection of links which for any
higher througput are undesireable anyways

therefore in many community networks we usually use a higher multicast rate.
