I see you are basing off the v1 of this patch. You need to send all the changes in one go.
So, include the missing code in rte_cuckoo_hash.c, and include rte_hash_set_cmp_func
in rte_hash_version.map, but don't remove it from DPDK_2.1, as it does not exist now.
In other words, create a patch from the current head of mainline, send it as a v3,
include the changes you made from v1->v2 and v2->v3 and send it again (and don't forget to use --in-reply-to).
Plus, remove the "to ver DPDK_2.2" part from the tile of the patch.

Thanks!
Pablo
