IB/mlx4: Add IPoIB checksum offload support
ConnectX 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.
