Number two, using ifconfig, count how many or see how many packets have been received. And then number three, using the kernel tracing, count the number of times your interrupt function was called, wait 10 seconds and do it again. So let's give this all a try. Well, let's see what interfaces we have. We can look at proc/net/dev. It's a little bit hard to read there, but you might see the wlp3s0, that's my WiFi interface. ethtool -i, we give that interface. And it says the driver is IWL WiFi. There you go. The second question is using ifconfig, show how many packets, one of your network interfaces has received. Well, I'm using my wired interface, so I'll look at that. So I'm going to go ifconfig, eno1, and then I'm going to grep for RX…
