Subject: [dpdk-dev] [PATCH v1 10/15] examples/l2fwd: optimize check for master core
Date: Thu, 14 Jun 2018 15:47:52 +0530	[thread overview]
Message-ID: <1528971477-14156-11-git-send-email-anoob.joseph@caviumnetworks.com> (raw)
In-Reply-To: <1528971477-14156-1-git-send-email-anoob.joseph@caviumnetworks.com>

v1:
* Replaced 'unsigned' with 'unsigned int'

Replacing the check for lcore_id & mastercore_id with the check for a
flag.
