Please keep the alphabetical order.

The skeleton aims to show a minimal piece of code (but bigger than hello world).
For any other usage, I think the "l2fwd" name is more appropriate.

It cannot be enabled everytime, because of the dependency.
We already have this problem with examples/vm_power_manager
and libvirt dependency. It must be solved by improving the build system.

In this case, we can simply use the variable PQOS_LIBRARY_PATH to
enable the build.

[...]
> +# Default location of PQoS library and includes,
> +# can be overridden by command line or environment
> +PQOS_INSTALL_PATH ?= /usr/local/

This default value is useless because we should detect the dependency
before trying to compile.

[...]
> +LDLIBS += $(PQOS_LIBRARY_PATH) \

Why this backslash?
