Subject: [dpdk-dev] [PATCH 2/4] app/test: add new buffer comparison macros
Date: Fri, 6 May 2016 14:58:46 +0100 [thread overview]
Message-ID: <1462543128-26604-3-git-send-email-pablo.de.lara.guarch@intel.com> (raw)
In-Reply-To: <1462543128-26604-1-git-send-email-pablo.de.lara.guarch@intel.com>
In order to compare buffers with length and offset in bits,
new macros have been created, which use the previous compare function
to compare full bytes and then, compare first and last bytes of
each buffer separately.
