[B.A.T.M.A.N.] pull request: batman-adv 2013-10-13

[Antonio Quartulli <antonio@meshcoding.com>]

Hello David,

this is our second pull request intended for net-next/linux-3.13.

The most important piece in this patchset is the new packet fragmentation code
implemented by Martin Hundebøll during his Google Summer of Code 2012[1]. This
code is entirely substituting the current fragmentation mechanism.

Other than this you have:
- the creation of a common BAT ICMP header which makes the ICMP subsystem more
  flexible and extensible
- the addition of a dummy rx mode handler for the soft-interface which allows
  users to set static multicast listeners
- some minor improvements and code cleanups


Please pull or let me know of any problem.

Thank you very much,
		Antonio

  batman-adv: Add dummy soft-interface rx mode handler (2013-10-12 17:17:12 +0200)

----------------------------------------------------------------
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
