The changes in the driver are mainly due to changes in the DMA descriptor provided by the Hip06 ethernet hardware. These changes need to co-exist with already present Hip05 DMA descriptor and its operating functions. The decision to choose the correct type of DMA descriptor is taken dynamically depending upon the version of the hardware (i.e. V1/hip05 or V2/hip06, see alredy existing hisilicon-hns-nic.txt binding file for detailed description). other changes includes in SBM, DSAF and PPE modules as well. Changes affecting the driver related to the newly added ethernet hardware features in Hip06 would be added as separate patch over this and subsequent patches.
