IB/cma: Add configfs for rdma_cm
Users would like to control the behaviour of rdma_cm. For example, old applications which don't set the required RoCE gid type could be executed on RoCE V2 network types. In order to support this configuration, we implement a configfs for rdma_cm. In order to use the configfs, one needs to mount it and mkdir <IB device name> inside rdma_cm directory. The patch adds support for a single configuration file, default_roce_mode. The mode can either be "IB/RoCE v1" or "RoCE v2".
