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".

Userspace InfiniBand Management Datagram (MAD) support. This

is the kernel side of the userspace MAD support, which allows

Userspace InfiniBand access support. This enables the

kernel side of userspace verbs and the userspace
|
|
communication manager (CM). This allows userspace processes
|
|
to set up connections and directly access InfiniBand

hardware for fast-path operations. You will also need
|
|
libibverbs, libibcm and a hardware driver library from
|
