4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Sunil Goutham <[email protected]> [ Upstream commit fa6d7cb5d76cf0467c61420fc9238045aedfd379 ] Don't offload IP header checksum to NIC. This fixes a previous patch which enabled checksum offloading for both IPv4 and IPv6 packets. So L3 checksum offload was getting enabled for IPv6 pkts. And HW is dropping these pkts as it assumes the pkt is IPv4 when IP csum offload is set in the SQ descriptor.
