Subject: [dpdk-dev] [PATCH v3 1/3] ethdev: improvement for constant usage
Date: Mon, 20 Oct 2014 10:58:16 +0800
Message-ID: <1413773898-24137-2-git-send-email-helin.zhang@intel.com> (raw)
In-Reply-To: <1413773898-24137-1-git-send-email-helin.zhang@intel.com>

Forced type conversion is not needed to define a macro with
constant. The alternate is to let compiler use the default width,
or specify the width with suffix of 'U', 'UL', 'ULL', etc.
