PRP trailer is 6 bytes of PRP protocol unit called RCT, Redundancy Control Trailer (RCT) similar to HSR tag. PRP network can have traditional devices such as bridges/switches or PC attached to it and should be able to communicate. Regular Ethernet devices treat the RCT as pads. This patch adds logic to format L2 frames from network stack to add a trailer (RCT) and send it as duplicates over the slave interfaces when the protocol is PRP as per IEC 62439-3. At the ingress, it strips the trailer, do duplicate detection and rejection and forward a stripped frame up the network stack.
