Thank you for spotting this -- the UDP-Lite code indeed ignores sk_no_check
and will (if no socket options are set) emulate UDP with sk_no_check = 0. Setting
it to 1 will make no difference; so the above is more not strictly necessary. Will
remove in next patch.
Any other comments or ideas, please do not hesitate to write.
