Ezequiel Garcia 3ae8f4e0b9 net: mv643xx_eth: Implement software TSO 
Now that the TSO helper API has been introduced, this commit makes use
of it to add support for software TSO in this driver.

This feature allows to improve outbound throughput performance significantly.
Running iperf tests shows a 30% improvement, tested on a Kirkwood Openblocks
A6 board.

This commit is just an example of the usage of the TSO API, it works fine
but needs some more work. In particular, the descriptor unmapping path must
avoid unmapping the TSO headers.
