DESCRIPTION

       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 value.  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.
