| Subject: net: aquantia: fix rx checksum offload for UDP/TCP over IPv6 |
| |
| From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com> |
| |
| [ 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. |
| |
| Fixes: 018423e90bee ("net: ethernet: aquantia: Add ring support code") |
