With the 7.3 kernel update I'm now getting rdma service startup failure messages: Dec 15 18:20:44 cscomp2 rdma-init-kernel: modprobe: FATAL: Module ib_mad not found.

Dec 15 18:20:44 cscomp2 systemd: Unit rdma.service entered failed state. Dec 15 18:20:44 cscomp2 systemd: rdma.service failed. This is more cosmetic than anything else I think, but I believe we need an update to rdma-7.3_4.7_rc2-5.el7 to resolve this.
