This patch changes the i40e driver to start using the new virtchnl
interface header file, and removes an already existing duplicate of the
i40e_virtchnl.h file contained in the i40e directory.

This patch adds a capability negotiation between VF and PF using ENCAP/
ENCAP_CSUM offload flags in order for the VF to support outer checksum
and TSO offloads for encapsulated packets. These capabilities were assumed
by default and enabled in current hardware. Going forward, these features
needs to be negotiated with PF before advertising to the stack.
Additionally, strip out the mac.type checks for X722 since outer checksums
are enabled based on the ENCAP_CSUM offload negotiation flag and maintain
consistency between drivers in how the features are configured.

Group together the minimum set of offload capabilities that are always
supported by VF in base mode. This define would be used by PF to make
sure VF in base mode gets minimum of base capabilities .

Add ENCAP_CSUM offload negotiation flag. Currently VF assumes checksum
offload for encapsulated packets is supported by default. Going forward,
this feature needs to be negotiated with PF before advertising to the
stack. Hence, we need a flag to control it.
This is in regards to prepping up for VF base mode functionality support.

Add opcodes and structures to support RSS configuration by PF driver on
behalf of the VF drivers. This reduces complexity in the VF driver and
allows us to support future hardware designs without modifying the VF
driver.

This patch adds a Client interface for i40iw driver
support. Also expands the Virtchannel to support messages
from i40evf driver on behalf of i40iwvf driver.
This client API is used by the i40iw and i40iwvf driver
to access the core driver resources brokered by the i40e driver.

X722 supports Expanded version of TCP, UDP PCTYPES for RSS.
Add a Virtchnl offload to support this.
Without this patch with X722 devices, driver will set wrong PCTYPES
for VF and UDP flows will not fan out.

X722 has a way to work around the descriptor WB issue,
this offload helps turn that feature on.

This opcode is not required. VFs that program RSS through the firmware
do it by interacting directly with the firmware, and do not need to use
the virtual channel for this functionality.

To prepare for the changes coming up in the X722 device and future
devices, the virtual channel interface has to change slightly. The VF
driver can now report what its capable of supporting, which then informs
the PF driver when it sends the configuration information back to the
VF.
A 1.1 VF driver on a 1.0 PF driver should not send its capabilities.
Likewise, a 1.1 PF driver controlling a 1.0 VF driver should not expect
or depend upon receiving the VF capabilities.
All other aspects of the API are unchanged.

Until the time a more robust versioning scheme is needed/implemented all
established virtual channel opcode values should remain consistent between
updates to the opcode enum.
This patch repositions I40E_VIRTCHNL_OP_CONFIG_RSS to the end of the enum. In
its current position this opcode displaces the initial value of
I40E_VIRTCHNL_OP_EVENT and will cause PF/VF compatibility issues.
Going forward the expectation is either:
a) All future opcode additions will be added as the last element of the
enum. Once VF drivers start making use of the new commands the virtual
channel version will need to be incremented and drivers will need to
implement a simple version check whereby VF drivers can only load on
PFs with a >= version.
b) or, if needed, design and implement a more complicated API
negotiation capability.
In either case PF drivers should always maintain backwards compatibility with
earlier VF driver versions.

Add the Virtual Channel OP event opcode for CONFIG_RSS, so that the
Virtual Channel state machine can properly decipher status change events.

1. There is no ixgbe_watchdog_task function in the driver, so change
the comment to the correct function name, i40e_watchdog_subtask.
2. Remove num_msix_entries from interrupt set_up routine
because it is never used.
3. Remove some TBD comments that are not needed.

While not part of this patch series, an i40evf driver is on its
way, and uses these files to communicate to the PF driver.

PF to VF interface.
