From: Gaetan Rivet Date: Sat, 15 Jul 2017 17:59:27 +0000 (+0200) Subject: devargs: restore device type API X-Git-Tag: spdx-start~2461 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=39f403e0d5bbba765a42baf975b06ea4736c4cc7;p=dpdk.git devargs: restore device type API Revert "devargs: make device types generic" This commit broke the rte_devargs API by changing the meaning of the rte_devtype enum. Restore the previous API, unit tests and function calls. Introduce parallel enum that acts as translation between previous API and current structures. Restoring the previous API means that -w and -b are not usable anymore with any bus having implemented the "parse" operation. Only PCI devices can be used with -w and -b, virtual devices are declared using vdev. This (partially) reverts commit bd279a79366f50a4893fb84db91bbf64b56f9fb1.
