[libfabric-users] verbs provider scatter-gather

Hi Libfabric users,

vrb_mr_regv returns FI_EINVAL if count (the number of entries in the iovec) is larger than 1:

                if (OFI_UNLIKELY(count > 1))
                                return -FI_EINVAL;

To the best of my knowledge, libibverbs supports scatter-gather, so why is this check present?  Did I miss some configuration that redefines the OFI_ UNLIKELY macro?

Thanks in advance,
