[dpdk-dev] [PATCH] hash: move field hash_func_init_val in rte_hash struct

[dpdk-dev] [PATCH] hash: move field hash_func_init_val in rte_hash struct

[Pablo de Lara]

In order to keep the ABI consistent with the old hash library,
hash_func_init_val field has been moved, so it remains
at the same offset as previously, since hash_func and
hash_func_init_val are fields accesed by the public function
rte_hash_hash and must keep the same offset as older versions.
