The MTU is currently defined layer dependent, but for some boards it is just to big. This issue proposes to make it board-dependent. When you're at it: make all packet buffers MTU dependent.

Things to do:

  • implement path MTU discovery for IPv6
  • are their similar mechanisms for other protocols (CCN-lite, ...)?
  • add MTU macro to all cpu_conf.h
  • make packet buffers MTU dependent
