You are absolutely right; the MCA parameter names between the oob and
btl tcp modules were slightly different (btl_tcp_if_[in|ex]clude and
oob_tcp_[in|ex]clude). And the FAQ is wrong -- I just updated it;
sorry about that, and thanks for pointing it out!

I literally just fixed this on the trunk this morning (https://
svn.open-mpi.org/trac/ompi/changeset/14746): both oob and btl tcp
modules now use the form *_if_[in|ex]clude. The old oob_tcp names
still exist as deprecated synonyms in case anyone is still using them.

I don't know if this change will make it over to a future 1.2.x
release or not.
