Hi,

here is the third version of the throughput meter support. It is just a
rebased version of the patchset with two little bugfixes. Both problems were
detected and reported by Antonio:

 * batctl didn't check if the test_time is > 0 before doing a division
 * batman-adv wasn't returning an error to batctl when dst was not reachable


I am currently unsure how we should proceed regarding the ICMP packet type
used to communicate to the userspace ([PATCH 2/3]). Andrew+Matthias already
prepared a netlink patchset which looks quite good and which should be
tested+applied. The consequence for this patchset would be that patch 2 should
be completely dropped and instead the tp_meter should become its own command
in the netlink interface of batman-adv. Any opinions about that (order in
which patches should be applied/netlink interface should be handled) by the
Simon, Antonio, Marek, Matthias or Andrew?


Antonio Quartulli (4):
      batman-adv: return netdev status in the TX path
      batman-adv: use another ICMP packet when sending command from userspace
      batman-adv: throughput meter implementation
      batctl: introduce throughput meter support
