From: Taku Izumi <izumi.t...@jp.fujitsu.com> [ Upstream commit fe8daf5fa715f7214952f06a387e4b7de818c5be ]
This patch fixes netdev->features for Extended Socket network device. Currently Extended Socket network device's netdev->feature claims NETIF_F_HW_CSUM, however this is completely wrong. There's no feature of checksum offloading. That causes invalid TCP/UDP checksum and packet rejection when IP forwarding from Extended Socket network device to other network device. NETIF_F_HW_CSUM should be omitted. Signed-off-by: Taku Izumi <izumi.t...@jp.fujitsu.com> Signed-off-by: David S.
