Disable packet type parsing as l2fwd doesn't rely on packet types.

Should we use the return value, and print a log perhaps, my concern is static
analysis tools will complain about unchecked return value.

And to prevent the noise, don't log on -ENOTSUP error, wdyt?

Can you please add the experimental API as comment, it may help removing these
flags when APIs becomes non-experimental.

Some thing for meson.
