I think it'll return an error only if:

* it queued the frame to the tail of the drbd;
* it then tried to transmit a frame from the head of the drbd;
* it failed to transmit the first frame in the drbd and it couldn't
put it back into the queue for whatever reason.

So I think it should be "ok enough" for both TCP and SCTP.

Give it a go and let me know how it goes.

It's an interesting architectural problem to completely solve.
