This rework of comments are basically related to: 1) styling of the code, 2) RSS default Key initiailization related code 3) redundant code removal PATCH V4: This addresses the review comment provided by Sergei Shtylyov. The changelog of every patch has also been modified. PATCH V3: Addresses the review comment floated by David Miller PATCH V2: 1) Bug Fixes and Clean-up: Internally identified 2) Addresses internal review comments by Kenneth Lee and by Huang Daode 3) Addresses the review comment from "Yisen.Zhuang(Zhuangyuzeng)" 4) Adds fix from Fengguang Wu for an error generated from "kbuild test robot" from Intel 5) Ethtool support for TSO set option from Lisheng PATCH V1: Adds initial support of Hip06 SoC with below changes: This patch-set adds support of new Hisilicon Hip06 SoC to the existing (already part of net-next) HNS ethernet driver for Hip05 SoC. Hip06 is a multi-core SoC and is a derivative of Hip05 SoC with lots of new hardware featres supported like RSS, TSO, hardware VLAN assist etc. The changes in the driver are mainly due to following: 1) 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 already existing hisilicon-hns-nic.txt binding file for the detailed description version and naming). 2) To support new features added to the Hip06 ethernet hardware: a. RSS (Receive Side Scaling) b. TSO (TCP Segment Offload) c. Hardware VLAN support (currently we are initializing hardware to not assist in stripping the vlan tag at hardware level. Proper support of this feature and ethtool would come after these patches have been accepted) Kindly note that, this patchset has been based on latest net-next.
