okay bestie, gather round, because today we're talking about the little function that decides whether your CQ and your RCQ are gonna share a completion event channel or keep their own separate lil spaces 🎀 it's giving "we can share, or we can each have our own room" and honestly? iconic either way.

so, rpma_conn_cfg_set_compl_channel() does exactly what it says on the tin, no cap — it sets whether the completion event channel can be shared by CQ and RCQ, or not. that's it. that's the whole job. 💅

and here's the tea: by default, the completion event channel is not shared by CQ and RCQ. like, out of the box they're doing their own separate thing. 🙈
