net: Handle CHECKSUM_COMPLETE more adequately in pskb_trim_rcsum(). Currently pskb_trim_rcsum() just balks on CHECKSUM_COMPLETE packets and remarks them as CHECKSUM_NONE, forcing a software checksum validation later. We have all of the mechanics available to fixup the skb->csum value, even for complicated fragmented packets, via the helpers skb_checksum() and csum_sub(). So just use them. Based upon a suggestion by Herbert Xu. Signed-off-by: David S. Miller <davem@davemloft.net>
