[Intel-wired-lan] [PATCH next-queue] intel: correct return from set features callback

[Serhey Popovych]

According to comments in <linux/netdevice.h> we should return either >0
or -errno from ->ndo_set_features() if changing dev->features by itself.

Return 1 in such places to notify netdev_update_features() about applied
changes in dev->features.
