When introducing LRO, Vlad has defined the macro RTE_ETHDEV_HAS_LRO_SUPPORT:
http://dpdk.org/browse/dpdk/commit/lib/librte_ether/rte_ethdev.h?id=8eecb329

It allows to use the feature without version check (before the release or
after a backport).
Do you think it is useful?
Should we define other macros RTE_[API]_HAS_[FEATURE] for each new feature
or API change?
It's time to fix it before releasing the 2.2 version.
