From: Pablo de Lara Date: Tue, 21 Jul 2015 14:10:19 +0000 (+0100) Subject: hash: move struct field to keep ABI stable X-Git-Tag: spdx-start~8667 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=9cd270a67856eb8d4ae43e5c84ff5390c6cb4eed;p=dpdk.git hash: move struct field to keep ABI stable 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 accessed by the public function rte_hash_hash and must keep the same offset as older versions.
