Did you enable network coding? That would explain the message, as NC
uses a larger header to make decoding possible at the receiver side.
As far as I can tell from a quick look in packet.h, the required MTU
should be 1532 now. (10 bytes unicast + 8 bytes extra for unicast_4addr
+ 14 ethernet = 32 bytes). Or am I bad at counting bytes?
