====================
octeontx2-af: NIX and NPC enhancements

This patchset is a continuation to earlier submitted four patch
series to add a new driver for Marvell's OcteonTX2 SOC's
Resource virtualization unit (RVU) admin function driver.

1. octeontx2-af: Add RVU Admin Function driver
   https://www.spinics.net/lists/netdev/msg528272.html
2. octeontx2-af: NPA and NIX blocks initialization
   https://www.spinics.net/lists/netdev/msg529163.html
3. octeontx2-af: NPC parser and NIX blocks initialization
   https://www.spinics.net/lists/netdev/msg530252.html
4. octeontx2-af: NPC MCAM support and FLR handling
   https://www.spinics.net/lists/netdev/msg534392.html

This patch series adds support for below

NPC block:
- Add NPC(mkex) profile support for various Key extraction configurations

NIX block:
- Enable dynamic RSS flow key algorithm configuration
- Enhancements on Rx checksum and error checks
- Add support for Tx packet marking support
- TL1 schedule queue allocation enhancements
- Add LSO format configuration mbox
- VLAN TPID configuration
- Skip multicast entry init for broadcast tables

v2:

- Rename FLOW_* to NIX_FLOW_* to avoid serious global namespace collisions,
as we have various FLOW_* definitions coming from
include/uapi/linux/pkt_cls.h for example.(David Miller)
- Pack the arguments of rvu_get_tl1_schqs() function
as 80 columns allows.(David Miller)
