reference prrte docs for prrte tcp related mca parameters.

also need/want to investigate the corresponding PRRTE
parameters that control use of network interfaces by the runtime
(e.g., communications setup and coordination during
``MPI_INIT`` and ``MPI_FINALIZE``) using the `prte_info command <https://docs.prrte.org/en/latest/man/man1/prte_info.1.html>`_.

I just tested this to be sure, but in the v5.0.x tarball (and therefore likely the main/v6.0.x tarballs), we include the prte_info.1 HTML man page. Is there a way we can link to that here, rather than linking to the one in docs.prrte.org?

what happens if an external prrte/openpmix is used? i'm not seeing any prrte or pmix htmls in the <install_dir>/share/doc in that event.

We do some complicated stuff in Makefiles about copying PRTE RSTs -- even from external PRTE installs -- to our RST tree and then building our docs (this only happens if you have Sphinx, of course).

If you build with external PRTE and don't have Sphinx, this doesn't happen, of course. In that case, IIRC (it's been a little while since I checked), we put in template "you didn't get docs because you don't have Sphinx" documentation.

PMIx can do network params too: PMIX_MCA_ptl_if_include/exclude

However it's true that you can't totally disable it
