[Bridge] [PATCH net-next] bridge: Add ability to always enable TSO/UFO

[Toshiaki Makita]

Currently a bridge device turns off TSO/UFO features if no bridge ports
support it. We can always enable them, since packets can be segmented
on ports by software as well as on the bridge device.
This will reduce the number of packets processed in the bridge.
