This is usually caused by a driver (in this case mac80211) implementing ndo_set_features, but I never accepted that patch as far as I remember, it's pending in patchwork. I don't see that in your tree either, so that's very puzzling. Clearly it's trying to turn off NETIF_F_GSO, as it should since the drivers both don't advertise NETIF_F_SG right now. The code you're looking at is in __netdev_update_features(), but I can't explain how it would get into this message if ndo_set_features is NULL. Perhaps you should recompile the kernel from scratch. johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
