Surely, we can also add the keyword. Given that unintended fallthrough is
already protected by the "MISSING_BREAK" and that fallthrough comments are
already used in DPDK, I thought it made sense to ignore the check.

If you prefer to add the keyword, let me ask:
- Where is the right place for it? Maybe rte_common.h?
- Should all the comments be replaced with the pseudo-keyword?

OK. I'll reorder it if the final decision is to ignore the check.

Thanks
