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.

Extend br_netlink to be able to create/delete MRP instances. The current
configurations options for each instance are:
- set primary port
- set secondary port
- set MRP ring role (MRM or MRC)
- set MRP ring id.
To create a MRP instance on the bridge:
$ bridge mrp add dev br0 p_port eth0 s_port eth
This patch implements the core MRP state-machines and generation/parsing of the
frames. The implementation is on top of the bridge.
All MRP frames are received by the function 'br_mrp_recv' which adds the frame
in a queue to process them. For each frame it needs to decide if the frame needs

To integrate MRP into the bridge, the bridge needs to do the following:
- notify when the link of one of the ports goes down or up, because MRP instance
needs to react to link changes by sending MRP frames.
- notify when one of the ports are removed from the bridge or when the bridge
is destroy
