In this patchset the rx-flow filters functionality and vlan filter offloads
are implemented.

The rules in NIC hardware have fixed order and priorities.
To support this, the locations of filters from ethtool perspective are also fixed:

* Locations 0 - 15 for VLAN ID filters
* Locations 16 - 31 for L2 EtherType and PCP filters
* Locations 32 - 39 for L3/L4 5-tuple filters (locations 32, 36 for IPv6)

Dmitry Bogdanov (6):
