The 10.4.3 firmware with congestion control
guarantees that each peer has only a single
peer_id mapping.
The 1:1 mapping isn't the case for older firmwares
(e.g. 10.4.1, 10.2, 10.1) but it should not
matter. This 1:1 mapping is going to be only used
by future code which inherently (flow-wise) is for
10.4.3.
