From: Pablo de Lara Date: Wed, 4 Oct 2017 03:46:09 +0000 (+0100) Subject: app/crypto-perf: parse segment size X-Git-Tag: spdx-start~1413 X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=083de3eba72f99cbd564576652d7e1e4a62fad47 app/crypto-perf: parse segment size Instead of parsing number of segments, from the command line, parse segment size, as it is a more usual case to have the segment size fixed and then different packet sizes will require different number of segments.
