Juhani Krekelä 9513911377 Pad the frame to the required length. 
If we don't do that, the NIC will generate padding that contains
non-zero bytes. EtherMess excepts all-zero padding, so this will break.

EtherMess

EtherMess is a protocol for direct messaging over bare Ethernet as well as a reference implementation for it in C and Python.

Building and installing

Build with make and install with make install. If you are installing somewhere other than the default of /usr/local, please set PREFIX to that location during both build and installation steps.

make install will tell you how to set the correct capability on ethermess-backend to allow running it as a normal user.

Protocol documentation

Description of the EtherMess protocol is provided as a man page ethermess.7. The description is contractual, and may not change in incompatible ways unless the version number in the EtherMess packets is updated.

Additionally a description of the protocol spoken between ethermess-backend and ethermess is provided to help understand the code and develop alternative frontends. The description is non-contractual and the protocol may change with future versions of ethermess.
