Details of the problem
ompi_info does not list parameters for the vader layer when vader is requested explicitely.
However, it does list vader parameters when btl all or all all are requested.
I also observe this behaviour on RHEL 7.3 ppc64le.
$ ompi_info --param btl vader --level 9
MCA btl: vader (MCA v2.1.0, API v3.0.0, Component v2.1.1)
$ ompi_info --param all all --level 9 | grep vader
MCA btl: vader (MCA v2.1.0, API v3.0.0, Component v2.1.1)
MCA btl vader: ---------------------------------------------------
MCA btl vader: parameter "btl_vader_free_list_num" (current value: "8", data source: default, level: 9 dev/all, type: int)
MCA btl vader: parameter "btl_vader_free_list_max" (current value: "4096", data source: default, level: 9 dev/all, type: int)
MCA btl vader: parameter "btl_vader_free_list_inc" (current value: "64", data source: default, level: 9 dev/all, type: int)
...
MCA btl vader: parameter "btl_vader_bandwidth" (current value: "40000", data source: default, level: 5 tuner/detail, type: unsigned_int)
