sfc: Set ip_summed correctly for page buffers passed to GRO
Page buffers containing packets with an incorrect checksum or using a protocol not handled by hardware checksum offload were previously not passed to LRO. The conversion to GRO changed this, but did not set the ip_summed value accordingly. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
