[ Upstream commit 2851349ac351010a2649e0ff86a1e3d68fe5d683 ]
The ndo_start_xmit field in net_device_ops is expected to be of type netdev_tx_t (*ndo_start_xmit)(struct sk_buff *skb, struct net_device *dev).
The mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition.
Again, not needed in any stable branches, thanks.
