If it is trivial, i don't see why you are so worried about abstracting
it?

Agreed.
Horatiu, could you also give some references to the frames that need
to be sent. I've no idea what information they need to contain, if the
contents is

Hi Horatiu and Stephen,
Horatiu, thanks for giving this a try. I am looking forward to maybe someday
be able to run ERPS on white box switches.

Media Redundancy Protocol is a data network protocol standardized by
International Electrotechnical Commission as IEC 62439-2. It allows rings of
Ethernet switches to overcome any single failure with recovery time faster than
STP. It is primarily used in Industrial Ethernet applications.
