To clarify, an FMR Work Request is simply posted to the SendQ like any other Work Request (of course the QP has to be privileged, or it will complete in error). An SQ Post should never block.
This would require hardware support, wouldn't it? eHCA2 doesn't have this kind of support, so FMR WRs are not an option here. J.
