|  Please don't add protocol-specific stuff to generic functions.  In this
|  case why don't you just ignore sk_no_check for UDPLITE as we do for TCP?

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.
