Subject: [dpdk-dev] [PATCH 16/22] virtio: Free mbuf's with threshold
Date: Thu, 15 Jan 2015 13:15:24 +0800	[thread overview]
Message-ID: <1421298930-15210-17-git-send-email-changchun.ouyang@intel.com> (raw)
In-Reply-To: <1421298930-15210-1-git-send-email-changchun.ouyang@intel.com>

This makes virtio driver work like ixgbe. Transmit buffers are
held until a transmit threshold is reached. The previous behavior
was to hold mbuf's until the ring entry was reused which caused
more memory usage than needed.
