Two new options in uci config:
* smoothing_half_time (-M)
Specify the half-time in seconds of the exponential decay used for
smoothing metrics for performing route selection; the value 0 disables
smoothing. The default is 4s.
* random_router_id (-r)
Use a random router-id. The default is to use persistent router-ids
derived from the MAC address of the first interface, which is easier
to debug and more reliably prevents routing loops but may sometimes
cause a node to be unreachable for 120 seconds just after boot.
Upstream changes:
3 May 2013: babeld-1.4.0
* Change the route selection algorithm to used a smoothed metric in
addition to the "real" metric. This reduces the amount of route
flapping without any special case hacks.
* New flag -r, use a random router-id. This avoids temporarily
unreachable nodes after a reboot when persistent storage is not
available.
* INCOMPATIBLE CHANGE: the local interface now announces the local
hostname, and marks the end of the initial route dump. (Thanks to
Gabriel Kerneis.)
* The local interface is now able to accept multiple simultaneous
connections.
* Detect BATMAN interfaces, don't assume they are wired.
