Thanks Simon. So, at least in UDP raw mode, the return value of low_level_output() climbs up to the original call (e.g. udp_send()). (forward-tracking was much easier than backtracking!) And the @note actually means: "Try your best to enqueue the packet. If you _really_ can't, return ERR_MEM."... Correct?
