together, so implement all functions in the MTL interface for all MTLs. The only places NULL was still being set was for add_comm/del_comm, and matched probe, both of which are straight forward to implement (or return ERROR_NOT_IMPLEMENTED, since the PML can't emulate matched probe). This commit was SVN r26194.
