If you execute linkloop(1M) back to the local interface’s own MAC
address, (linkloop(1M) to self) the local address will send a response. No
hardware is exercised.

netstat
The netstat command shows network status. It may be run with several
options. The example below shows the -i option that is used to obtain
inbound and outbound statistics for the IP interfaces.
The Ipkts (Inbound packets) and Opkts (Outbound packets) indicate the
IP packets received/sent via each interface. You can execute the netstat
-i command repeatedly to determine if an interface is sending/receiving
IP packets. You can also use it to get an approximation of the relative
traffic loads for the interfaces.
(Ipkts and Opkts shown in the following table are IP packets only)
