[NET]: Avoid unnecessary cloning for ingress filtering
As it is we always invoke pt_prev before ing_filter, even if there are no ingress filters attached. This can cause unnecessary cloning in pt_prev. This patch changes it so that we only invoke pt_prev if there are ingress filters attached. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
