You need to tell us where you cloned the `bmv2` and `p4c-bm` repositories
:). Please update the values of the shell variables `BMV2_PATH` and
`P4C_BM_PATH` in the `env.sh` file - located in this directory. Note that if you
cloned both repositories in the same directory as this one (`tutorials`), you
will not need to change the value of the variables.

You will also need to run the `veth_setup.sh` script included in this directory
as `sudo` to setup the veth interfaces needed by the switch.
