If anyone has any objections, please let me know. ------------------ From: Michal Swiatkowski [ Upstream commit 2d19302f628853742c4828381abbd668c1315598 ] skb_checksum_help() can fail. Pass its return value back to the caller. Commonize this software path in goto. Instead of just returning error try calculating software checksum first. There is a check for TSO in checksum_sw_fb.
