IB/mthca: Add IPoIB checksum offload support
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.
