From: Ori Kam Date: Mon, 6 Jul 2020 17:36:47 +0000 (+0000) Subject: regexdev: add core structures X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=9c26771bc58d7d91231b53128511a8e1e3e4cb77;p=dpdk.git regexdev: add core structures This commit introduce the rte_regexdev_core.h file. This file holds internal structures and API that are used by the regexdev.
