Subject: [dpdk-dev] [PATCH v2 16/24] virtio: Free mbuf's with threshold
Date: Tue, 27 Jan 2015 10:35:56 +0800 [thread overview]
Message-ID: <1422326164-13697-17-git-send-email-changchun.ouyang@intel.com> (raw)
In-Reply-To: <1422326164-13697-1-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.
