From: Fan Zhang Date: Tue, 18 Apr 2017 11:28:14 +0000 (+0100) Subject: crypto/scheduler: improve parameters parsing X-Git-Tag: spdx-start~3467 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=50e14527b9d14b340214412bfe9b6a8755933384;p=dpdk.git crypto/scheduler: improve parameters parsing This patch improves the cryptodev scheduler PMD's commandline parsing capability. Originally, the scheduler's slave option requires the slave vdev(s) being declared prior to it. This patch removes this limitation by storing the slave names temporarily and attaching them later.
