This patch adds capability to configure DCB on i40e network
interfaces using Intel XL710 adapter firmware APIs.

By default all VSIs are only enabled for the default traffic
class enabled by firmware for any given PF. The driver would
query the firmware for the traffic classes that are enabled for
the port and reconfigure the LAN VSI to match to the port traffic
class settings. All other VSIs are only enabled for the default
traffic class settings for now.

The driver registers and listens to firmware events that may
require change in the DCB settings. It may reconfigure the VSI
settings based on these events.

This patch exposes IEEE DCBNL interfaces for the i40e driver to
allow any application to query the DCB settings on the adapter.

Intel XL710 series of adapters support QoS as per the
IEEE 802.1 DCB (Data Center Bridging) standard.
This is supported in conjuction with:
- Enhanced Transmission Selection (ETS) - IEEE 802.1Qaz
- Priority Flow Control (PFC) - IEEE 802.1Qbb
- DCB eXchange Protocol (DCBX) - IEEE 802.1Qaz

On Intel XL710 adapters DCBX is performed by the adapter
firmware. The firmware runs DCBX in willing mode and configures
the port as per the DCB settings recommended by it's link
partner.

By default in absence of any DCBX; firmware would configure the
port with a single traffic class and all of the port bandwith
will be allocated to that traffic class.

This patch adds functions and calls to support querying and
configuring DCB using firmware APIs.

The i40e hardware was generating some inconsistent results
when using current programming methods.  This refactor
fixes the inconsistencies that were preventing clean
unloads of the driver, and moves the queues for handling
flow director errors into their own hardware VSI.

This patch also implements a corrected version of the
basic ethtool add ntuple rule, which will disable
the driver's automatic flow programming.  A future patch
adds remove/replay/list support for ntuple.

The i40e Physical Function (PF) driver will allow the
 Virtual Function (VF) driver to configure its own VLAN filters if no port
 VLAN filter has been configured.  This leads to the possibility of the
 administrator setting a port VLAN filter for the VF after the VF has already
 configured its own VLAN filters.  This leads to a conflict that can only be
 resolved by reloading the VF driver.  When the conflicting administrative
 command is detected in setting the port VLAN then log a message indicating to
 the system administrator that he must now reload the VF driver for the new
 port VLAN settings to take effect.
