Subject: [PATCH v4 net-next 00/13] Add ethtool ntuple filters support

This patch series adds support for ethtool ntuple filters, unicast
address filtering, VLAN offload and SR-IOV ndo handlers. All of the
above features are based on the Admin Function(AF) driver support to
install and delete the low level MCAM entries. Each MCAM entry is
programmed with the packet fields to match and what actions to take
if the match succeeds. The PF driver requests AF driver to allocate
set of MCAM entries to be used to install the flows by that PF. The
entries will be freed when the PF driver is unloaded.

* The patches 1 to 4 adds AF driver infrastructure to install and
  delete the low level MCAM flow entries.
* Patch 5 adds ethtool ntuple filter support.
* Patch 6 adds unicast MAC address filtering.
* Patch 7 adds support for dumping the MCAM entries via debugfs.
* Patches 8 to 10 adds support for VLAN offload.
* Patch 10 to 11 adds support for SR-IOV ndo handlers.
* Patch 12 adds support to read the MCAM entries.

Misc:
* Removed redundant mailbox NIX_RXVLAN_ALLOC.

Change-log:
v4:
- Fixed review comments from Alexander Duyck on v3.
	- Added macros for KEX profile configuration values.
	- TCP/UDP SPORT+DPORT extracted using single entry.
	- Use eth_broadcast_addr() instead of memcpy to avoid one extra variable.
	- Fix "ether type" to "Ethertype" & "meta data" to "metadata" in comments.
	- Added more comments.
v3:
- Fixed Saeed's review comments on v2.
	- Fixed modifying the netdev->flags from driver.
	- Fixed modifying the netdev features and hw_features after register_netdev.
	- Removed unwanted ndo_features_check callback.
v2:
- Fixed the sparse issues reported by Jakub.
