That's a leftover from the initial version I wrote which had also
support for IMS_MSI_QUEUE to store the message in queue memory, but we
have no use case yet for it.
But yes, as things stand now it does not make any sense and IIRC at the
end they do not share anything in the C file except for some includes at
the very end.
Thanks,
