[NET] back: Add SG support
This patch adds scatter-and-gather support to the backend. It also advertises this fact through xenbus so that the frontend can detect this and send through SG requests only if it is supported. SG support is required to support skb's larger than one page. This in turn is needed for either jumbo MTU or TSO. One of these is required to bring local networking performance up to a level that is acceptable. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
