       The  fi_control  operation is used to perform one or more operations on a fabric resource.  Conceptually,
       fi_control is similar to the POSIX fcntl routine.  The exact behavior of using fi_control depends on  the
       fabric  resource  being  operated  on, the specified command, and any provided arguments for the command.
       For specific details, see the fabric resource specific help pages noted below.

       fi_alias, fi_get_val, and fi_set_val are wrappers for  fi_control  with  commands  FI_ALIAS,  FI_GET_VAL,
       FI_SET_VAL,  respectively.  fi_alias creates an alias of the specified fabric resource.  fi_get_val reads
       the value of the named parameter associated with the fabric resource, while fi_set_val updates that  val‐
       ue.   Available  parameter  names  depend  on  the  type  of the fabric resource and the provider in use.
       Providers may define provider specific names in the provider extension header files  (’rdma/fi_ext_*.h’).
       Please refer to the provider man pages for details.
