From: David Marchand Date: Mon, 22 Sep 2014 08:37:59 +0000 (+0200) Subject: eal: merge bsd and linux common options parsing X-Git-Tag: spdx-start~10395 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=489a9d6c9f77;p=dpdk.git eal: merge bsd and linux common options parsing All common options are now in a single file. Common usage() has been moved as well.
