Remove the filter created by the firmware with the default MAC address it
reads out of the NVM storage and a promiscuous VLAN tag and replace it
with a filter that will not accept tagged packets by default.  The system
must request a VLAN tag packet filter to get packets with that tag.

Currently if the firmware reports DCB capability the driver enables
I40E_FLAG_DCB_ENABLED flag. When this flag is enabled the driver
inserts a tag when transmitting a packet from the port even if there
are no DCB traffic classes configured at the port.

This patch adds a new flag I40E_FLAG_DCB_CAPABLE that will be set
when the DCB capability is present and the existing flag
I40E_FLAG_DCB_ENABLED will be set only if there are more than one
traffic classes configured at the port.

In XL710 devices we program FD filter's fields from Tx perspective of the flow.
However the user interface exposed in ethtool should be compliant with the
previous generation of drivers where a filter src and dst field are from
the RX perspective. This patch changes the ethtool interface in this regard
to match the other drivers.

We tell the HW upper boundary of power of 2 in VSI config,
but the HW does not restrict us to use just power of 2 GPS in
case of RSS as long as we are not sharing the RSS table with
another VSI (VMDq). We at present are not doing RSS in VMDq
VSI.
If we were to enable that and if the system had CPU count which
was not power 2, the VMDq VSIs will see a little skewed distribution.

The number of VSIs that the firmware reports to us is a guaranteed
minimum, not an absolute maximum. The hardware actually supports far
more  than the reported value, which we often need.

To allow for this, we allocate space for a larger number of VSIs than is
guaranteed by the firmware, with the knowledge that we may fail to get
them all in the future.

Note that we are just allocating pointers here, the actual (much larger)
VSI structures are allocated on demand.

Check for error status bits on the AdminQ event queue and announce them

interrupt to get the driver's attention to process the ARQ, which will
likely be enough to clear the actual issue.

The TSO logic in the transmit path had some assumptions that
have been broken now that the kernel can send as much as 32kB
in a single skb->frag[.] entry, even on a system with 4kB pages.

This fixes the assumptions and allows the kernel to operate
as efficiently as possible with both SENDFILE and SEND.

In addition, the hardware limit of data contained in a descriptor is
changed to the next power of two below where it currently is in
order to align to a power of two value, preventing a single byte
of data in a descriptor.

Both the PF side and the VF side of the VF reset process are too noisy.
We already warn the user that a reset is happening, and that is
sufficient.

Because some of these message are inside if statements, we have to
rejigger the brackets at the same time to keep our coding style
consistent.
