  1. REF6976 Silent failure of OMPI over OFI with large messages sizes 

    INTERNAL: STL-59403

The OFI (libfabric) MTL does not respect the maximum message size
parameter that OFI provides in the fi_info data.

This patch adds this missing max_msg_size field to the mca_ofi_module_t
structure and adds a length check to the low-level send routines.

(cherry-picked from commit 3aca4af)
