Detailed Description

test for multihop path establishing and path error procedures Initiate scenario with 6 stations.

Procedure of opening peer link is the following: (PMP routines are not shown) 

*      1    2    3    4    5    6
*      |    |    |    |    |<---|--->  ARP request (first attempt has failed!)
*      |....|....|....|....|....|      ARP request
*      |<---|--->|    |    |    |      ARP request
*  <---|--->|    |    |    |    |      PREQ       } This order is broken
*  <---|--->|    |    |    |    |      ARP request} due to BroadcastDca 
*      |<---|--->|    |    |    |      PREQ
*      |....|....|....|....|....|      ARP request
*      |    |    |    |<---|--->|      PREQ
*      |    |    |    |    |<---|      PREP
*      |....|....|....|....|....|      PREP 
*      |<---|    |    |    |    |      PREP
*      |--->|    |    |    |    |      ARP response
*      |....|....|....|....|....|      ARP response
*      |    |    |    |    |--->|      ARP response
*      |    |    |    |    |<---|      Data
*      |....|....|....|....|....|      Data
*      |<---|    |    |    |    |      Data
*  <---|--->|    |    |    |    |      ARP request
*      |....|....|....|....|....|      ARP request
*      |    |    |    |    |<---|--->  ARP request
*      |    |    |    |    |<---|      ARP response
*      |....|....|....|....|....|      ARP response
*      |<---|    |    |    |    |      ARP response
*      |--->|    |    |    |    |      Data
* At 5 station number 4 disappears, and PERR is forwarded from 3 to 1
* and from 5 to 6, and station 6 starts path discovery procedure
* again:
*      |    |<---|         |--->|      PERR (one due to beacon loss and one due to TX error)
*      |<---|    |         |    |      PERR
*      |    |    |         |<---|--->  PREQ
*      |    |    |     <---|--->|      PREQ
*      |....|....|.........|....|      Repeated attempts of PREQ
*
