Merge tag 'batman-adv-for-davem' of git://git.open-mesh.org/linux-merge

Included changes:
- ensure RecordRoute information is added to BAT_ICMP echo_request/reply only
- use VLAN_ETH_HLEN when possible
- use htons when possible
- substitute old fragmentation code with a new improved implementation by
  Martin Hundebøll
- create common header for BAT_ICMP packets to improve extendibility
- consider the network coding overhead when computing the overall room needed by
  batman headers
- add dummy soft-interface rx mode handler
- minor code refactoring and cleanups
