DESCRIPTION

25       The fi_control operation is used to perform one or more operations on a
26       fabric resource.  Conceptually, fi_control is similar to the POSIX  fc‐
27       ntl  routine.   The  exact  behavior of using fi_control depends on the
28       fabric resource being operated on, the specified command, and any  pro‐
29       vided  arguments for the command.  For specific details, see the fabric
30       resource specific help pages noted below.
31
32       fi_alias, fi_get_val, and fi_set_val are wrappers for  fi_control  with
33       commands FI_ALIAS, FI_GET_VAL, FI_SET_VAL, respectively.  fi_alias cre‐
34       ates an alias of the specified fabric resource.  fi_get_val  reads  the
35       value of the named parameter associated with the fabric resource, while
36       fi_set_val updates that value.  Available parameter names depend on the
37       type of the fabric resource and the provider in use.  Providers may de‐
38       fine provider specific names in the  provider  extension  header  files
39       (’rdma/fi_ext_*.h’).   Please  refer  to the provider man pages for de‐
40       tails.
