I also tried to find how to do this for mv643xx_eth a few years ago based on other drivers (eg: tilegx) and failed to find anything common. At this level, we're really playing with the NIC's descriptors, and many of them have different capabilities (eg: HW checksums for all frames, VLAN or none, etc...). I don't really see how this could be factorized, and since many NICs do support TSO, I'm not convinced by the effort.
