Benjamin Herrenschmidt says:

====================
ftgmac100: Rework batch 3 - TX path

This is version 2 of the third batch of updates to
the ftgmac100 driver.

This one tackles the TX path of the driver. This provides the
bulk of the performance improvements by adding support for
fragmented sends along with a bunch of cleanups.

Version 2 fixes a patch splitting mistake and uses
eth_skb_pad() (which uses skb_put_padto) to pad ethernet
frames rather than skb_padto(), thus removing the need to
also pad the packet headlen in a couple of places.

Subsequent batches will add various features (ethtool functions,
vlan offlan, ...) and cleanups.
