MLNX_OFED 5.0?
And thus MLNX_OFED will become a much "thinner" add-on than currently?

1. Distro RDMA stack (rdma-core)
2. MLNX_OFED full
3. MLNX_OFED RPMS_UPSTREAM_LIBS

level of attention to correctness and performance as the glibc one.
Further, depending on how you provision accounts in your cluster, the
lack of NSS in musl might be a problem.
