| Subject: fjes: Fix wrong netdevice feature flags |
| |
| From: Taku Izumi <izumi.taku@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. |
