From fe8daf5fa715f7214952f06a387e4b7de818c5be Mon Sep 17 00:00:00 2001 From: Taku Izumi Date: Wed, 15 Mar 2017 13:47:50 +0900 Subject: [PATCH] fjes: Fix wrong netdevice feature flags 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.
