Prev: [RFC][PATCH v4 17/18] Add a kconfig entry and make entry for mp device.
Next: [RFC][PATCH v4 08/18] Ignore skb_reserve() when device is using external buffer.

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.
