Sorry for the dumb question but here goes.  The -i option must be the
device name for my wifi on my laptop, right? that interface will not see
any packets addressed to it to/from the AirTV.

when I did:  sudo tcpdump -i wlp0s20f3 -nn -s0 -w dump.cap host
I started watching OTA tv on which should have caused traffic between the
AirTV and my FireTV stick

But when I ctrl-c'ed to stop tcpdump, it captured 0 packets.  Which sort of
makes sense because the laptop is on

Can the laptop act like a monitor and watch the traffic? All my devices are
on 192.168.0.xx
