From: Pablo de Lara Date: Tue, 27 Jun 2017 21:16:33 +0000 (+0100) Subject: cryptodev: move vdev functions to a separate file X-Git-Tag: spdx-start~2948 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=63348b9d1c43895e56c7f1b0a0b2d8f66d4bffd0;p=dpdk.git cryptodev: move vdev functions to a separate file Move all functions handling virtual devices to a separate header file "rte_cryptodev_vdev.h", in order to leave only generic functions for any device in the rest of the files. It also creates the file "rte_cryptodev_pmd.c", with the implementations of these functions.
