Ethernet channel supervision functions

The protection relay offers a bandwidth rate limiting functionality to limit the
Ethernet/TCP network traffic. The main purpose of this feature is the possibility
to divide network segments for different multicast frame types and also to
limit the network congestion and traffic towards the protection relay processing
during network attacks (such as a Denial of Service attack) or in case of network
configuration issues.
See the cyber security deployment guideline for the Ethernet filter and rate limiter
functionality.
