Handle rsc packet with a single segment same as a multi segment rsc packet so that CHECKSUM_PARTIAL is set in the skb->ip_summed field. The current code is passing CHECKSUM_NONE resulting in TCP GRO layer doing checksum in SW and hiding the issue. This will fail when using dmabufs as payload buffers as skb frag would be unreadable.
