Subject: [RFC PATCH v10 03/16] Add a ndo_mp_port_prep pointer to net_device_ops.
Date: Sat, 11 Sep 2010 17:52:56 +0800 [thread overview]
Message-ID: <1284198789-5358-4-git-send-email-xiaohui.xin@intel.com> (raw)
In-Reply-To: <1284198789-5358-3-git-send-email-xiaohui.xin@intel.com>
From: Xin Xiaohui <xiaohui.xin@intel.com>
If the driver want to allocate external buffers,
then it can export it's capability, as the skb
buffer header length, the page length can be DMA, etc.
The external buffers owner may utilize this.
