datapath: Assert IFF_TX_SKB_SHARING on internal devices.
		
Linux 3.1 adds a flag to check whether it's OK for shared skbs to
be transmitted on devices.  This generally isn't a problem for
hardware devices but software devices such as OVS that hold state
in the skb need to clear the flag, which is enabled by default.

datapath: Add version check for struct netdev_ops.
		
Linux 3.1 drops the symbol HAVE_NET_DEVICE_OPS that lets us know
whether struct netdev_ops is present.  As a result, we need to
replace it with an explicit version check.
