// An Ethernet switch with Media Redundancy Protocol (MRP) support.
// It extends the standard EthernetSwitch by enabling the MRP functionality.
//
// MRP is a data network protocol standardized by IEC 62439-2 that allows rings of
// Ethernet switches to overcome any single network failure with recovery time of
// less than 200ms. It operates at the MAC layer and works by blocking one link in
// the ring to prevent loops, while monitoring the ring integrity to quickly restore
// connectivity if a failure occurs.
