Merge branch 'Support-of-Flow-Director-in-HNS3-Ethernet-Driver-for-HiP08-Rev2-SoC'

Salil Mehta says:

====================
Support of Flow Director in HNS3 Ethernet Driver for HiP08 Rev2 SoC

This patch-set adds the support of FD(Flow Director) in the HNS3 PF driver
for HiP08 Rev2(0x21) SoC of Hisilicon. FD can be used in filtering the flows
and deciding to drop the flow or forward it to paricular queue.

Configuration consists of rules with input keys and actions. The rules are
stored in TCAM.
