Djordje Nedic facab8c5a7 tools: Increase the minimal supported CMake version to 3.16 
This updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system.
This is the version that provides most new features and also the one we use in our latest docker image for CI.

Setup dummy network interfaces

sudo ip link add eth2 type dummy
sudo ip addr add 192.168.1.200/24 dev eth2
sudo ip link set eth2 up
sudo ifconfig eth2 multicast

Dig on a specified interface

dig +short -b 192.168.1.200 -p 5353 @224.0.0.251 myesp.local

Run avahi to browse services

Avahi needs the netif to have the "multicast" flag set

david@david-comp:~/esp/idf (feature/mdns_networking_socket)$ avahi-browse -a -r -p
