It depends on device driver. Some drivers access hardware counters
maintained by MAC and can display these counters with sysctl(8).
In addition these counters are used to update statistics counters
in ifnet which can be checked with netstat(1).
For example, em(4), age(4), sf(4), bge(4), bce(4) provide sysctl
interface.
