Arbel and Sinai devices support checksum generation and verification of TCP and UDP packets for UD IPoIB messages. This patch checks if the HCA supports this and sets the IB_DEVICE_UD_IP_CSUM capability flag if it does. It implements support for handling the IB_SEND_IP_CSUM send flag and setting the csum_ok field in receive work completions.
