CQ, not supporting a different subnet prefix per IB subnet is against
IB nature, I don't think there
should be any problem to configure a different prefix at each open SM
instance and the Linux host stack
would work perfectly under this config. If you are a ware to any
problem in the opensm and/or the host stack
please let the community know and the maintainers will fix it.
