13Device files
14
15The userspace CM uses a device file per adapter present.
16
17To create the appropriate character device file automatically with
18udev, a rule like
19
20    KERNEL="ucm*", NAME="infiniband/%k", MODE="0666"
21
22can be used.  This will create the device node named
23
24    /dev/infiniband/ucm0
25
26for the first HCA in the system, or you can create it manually
