[PATCH AUTOSEL for 4.4 026/101] fjes: Fix wrong netdevice feature flags

[alexander.levin@verizon.com]

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.
