net: Infrastructure for CHECKSUM_PARTIAL with remote checsum offload
This patch adds infrastructure so that remote checksum offload can set CHECKSUM_PARTIAL instead of calling csum_partial and writing the modfied checksum field. Add skb_remcsum_adjust_partial function to set an skb for using CHECKSUM_PARTIAL with remote checksum offload. Changed skb_remcsum_process and skb_gro_remcsum_process to take a boolean argument to indicate if checksum partial can be set or the checksum needs to be modified using the normal algorithm.
