Dear Med,
The logic we adopted for guessing complexity of a valid port and for the
whole range is as mentioned in

Mohamed, all,
First, thanks for the analysis draft. It sounds good. Let me try to bring my
thought.
An interesting point is here. In the algorithms which define offset to exclude
ports such as 1024, 4096 whatever, the efficiency of port utilization is
decreased, which algorithm is 4rd, and

I checked draft-despres-softwire-4rd-addmapping again and you reverse only
the L bits identifying the PSID. This is why I'm puzzled how it is possible
