4.19-stable review patch. If anyone has any objections, please let me know.
------------------ From: Dmitry Bogdanov <[email protected]> [ Upstream commit a7faaa0c5dc7d091cc9f72b870d7edcdd6f43f12 ] TCP/UDP checksum validity was propagated to skb only if IP checksum is valid. But for IPv6 there is no validity as there is no checksum in IPv6. This patch propagates TCP/UDP checksum validity regardless of IP checksum.
