In chip V2, the default value of port id in tx BD is Zero. If it is not
configurated to the other value, all management packets will be sent out
from port0. So port_id in the tx BD needs to be updated when sending a
management packet.
In V2 chip, when sending mamagement packets, the driver should
config the port id to BD descs.

This patch replace the assoication between dsaf and enet from string
matching to object reference. It requires the DTS to be updated within
BIOS. Thanks god it can be done for all released boards.

This patch adds the support of "TSO (TCP Segment Offload)" feature
provided by the Hip06 ethernet hardware to the HNS ethernet
driver.
Enabling this feature would help offload the TCP Segmentation
process to the Hip06 ethernet hardware. This eventually would help
in saving precious cpu cycles.

This patch adds the support of "RSS (Receive Side Scaling)" feature
provided by the Hip06 ethernet hardware to the HNS ethernet
driver.
This feature helps in distributing the different flows (mapped as
hash by hardware using Toeplitz Hash) to different Queues asssociated
with the processor cores. The mapping of flow-hash values to the
different queues is stored in indirection table (which is per Packet-
parse-Engine/PPE). This patch also provides the changes to re-program
the (flow-hash<->Qid) mapping using the ethtool.

This patchset adds support of Hisilicon Hip06 SoC to the existing HNS
ethernet driver.
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 already 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.

HNAE (Hisilicon Network Acceleration Engine) is a framework to provide a
unified ring buffer interface for Hisilicon Network Acceleration
Engines.
With the interface, upper layer can work as ethernet driver, ODP driver
or other service driver on purpose.
