Hi,

I think I have found a functional bug in ns3 dot11s mesh code:
It occurs, that a PREP that comes directly from the requested STA is
rejected for its old SN, which is not logical.


In ReceivePrep():
prep.GetOriginatorSeqNumber () is used to obtain the Sequence number
of the STA that answered the previous PREQ.
But according to the 802.11s draft 11C.10.7 Path Reply (PREP) the
Originator SN is the SN of the STA that sent the PREQ. The Target SN
or Destination SN is the correct value of the requested SAT and so
prep.GetDestinationSeqNumber() should be used instead.


Could somebody confirm this and firmly file a bug?

Regards
