Subject: [PATCH net-next 0/3] net: mvpp2: software TSO support

Hi all,

This series adds the s/w TSO support in the PPv2 driver, in addition to
two cosmetic commits. As stated in patch 3/3:

Using iperf and 10G ports, using TSO shows a significant performance
improvement by a factor 2 to reach around 9.5Gbps in TX; as well as a
significant CPU usage drop (from 25% to 15%).

Thanks!
Antoine
