net: Split sk_no_check into sk_no_check_{rx,tx}
Define separate fields in the sock structure for configuring disabling checksums in both TX and RX-- sk_no_check_tx and sk_no_check_rx. The SO_NO_CHECK socket option only affects sk_no_check_tx. Also, removed UDP_CSUM_* defines since they are no longer necessary. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
