Well as we discussed before, the size of the MFT is really independent
of the # of MCGs supported.  It's up to the SM how to allocate MLIDs,
and as long as all the switches in the fabric support at least one
MLID, then any number of MCGs can be managed by the SM.  So I would
say this is entirely an SM issue.
