Hi Xalex,

Thank you for doing this.

Can you reserve the csum_ok bits in the recv_opt field rather than adding an extra field?  This opens up the possibility in the future to have checksum offload for RC connections without needing to change the interfaces further.  It also removes the need for drivers to clear the field if checksum isn't supported (since the unused bits in the recv_opt field should be cleared).
