This counter increments each time the BCM5722 Ethernet controller receives a non-collision packet containing at least one
receive error (freezes at the maximum value FFFFh). The counter automatically clears when read.

S3MII Error Counter increments each time the BCM5722 Ethernet controller detects a S3MII overrun/underrun event. False
Carrier Sense Counter increments each time the BCM5722 Ethernet controller detects a false carrier on the receive input.
These counters freeze at the maximum value FFh. The counters automatically clear when read.
