+Date: November 29, 2015
+KernelVersion: 4.4.0
+Description: Interface is used to configure RDMA-cable HCAs in respect to
+ RDMA-CM attributes.
+
+ Attributes are visible only when configfs is mounted. To mount
+ configfs in /config directory use:
+ # mount -t configfs none /config/
+
+ In order to set parameters related to a specific HCA, a directory
+ for this HCA has to be created:
+ mkdir -p /config/rdma_cm/<hca>
+
+
