Subject: [dpdk-dev] [PATCH 22/22] ethdev: support setting maximum packet length to less than 1518
Date: Wed, 21 May 2014 23:30:21 +0800 [thread overview]
Message-ID: <1400686221-4696-23-git-send-email-helin.zhang@intel.com> (raw)
In-Reply-To: <1400686221-4696-1-git-send-email-helin.zhang@intel.com>
In ethdev, it will ignore setting maximum packet length to less than 1518.
The changes is to fix it and let less than 1518 can be really set for
maximum packet length.
