## Running the `embassy-net` examples

First, create the tap0 interface. You only need to do this once.
First, create the tap99 interface. (The number was chosen to
hopefully not collide with anything.) You only need to do
this once.

```sh
sudo ip tuntap add name tap0 mode tap user $USER
sudo ip link set tap0 up
sudo ip addr add 192.168.69.100/24 dev tap0
sudo ip -6 addr add fe80::100/64 dev tap0
sudo ip -6 addr add fdaa::100/64 dev tap0
sudo ip -6 route add fe80::/64 dev tap0
sudo ip -6 route add fdaa::/64 dev tap0
sudo sh tap.sh
```

Second, have something listening there. For example `nc -lp 8000`
