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".

Providers should tell IB core the wc's network type. This is used in order to search for the proper GID in the GID table. When using HCAs that can't provide this info, IB core tries to deep examine the packet and extract the GID type by itself. We choose sgid_index and type from all the matching entries in RDMA-CM based on hint from the IP stack and we set hop_limit for the IP packet based on above hint from IP stack.
