Subject: [net-next 1/6] e1000e: convert to netdev features/hw_features API
From: Bruce Allan <bruce.w.allan@...el.com>
Private rx_csum flags are now duplicate of netdev->features &
NETIF_F_RXCSUM. Remove those duplicates and use the net_device_ops
ndo_set_features. This is based on the original patch submitted by
Michał Mirosław <mirq-linux@...e.qmqm.pl>
