This implements receive offload for VXLAN for i40e. The hardware
supports checksum offload/verification of the inner/outer header.

This adds the implementation for the VXLAN ndo's. This allows the
hardware to do RX checksum offload for inner packets on the UDP ports
that VXLAN notifies us about.

Wake on LAN is disabled by default and will remain that way for most
platforms, but there is an NVM setting that allows vendors to enable it
for a port if they think they've provided the right power environment
for the device. This patch adds code to check the NVM setting and enable
Magic Packet use if WoL is enabled for the port.
Since only Magic Packet is supported, there's not a lot of HW configuration
needed.

Any user-initiated path which eventually calls reset needs
to hold the rtnl_lock, so add functionality to do that.
Be careful not to use the safe reset when cleaning up
from the diagnostic tests, which avoids rtnl_lock
recursion from ethtool.
Protect the reset_task with rtnl_lock, since it runs from a work item.

This is the second of 3 patches that allows for changing
the number of queues in the driver on the fly.
This patch adds a function that calls the reinit flow for the
main VSI after making changes to the RSS queue count as requested
by the user.

Add a quick ethtool test for interrupts using the SW interrupt.
Also, change the loopback test (for now) to not report failure.

Allocate the queue pairs individually instead of as a group. This
allows for much easier queue management as it is possible to dynamically
resize the queues without having to free and allocate the entire block.
Ease statistic collection by treating Tx/Rx queue pairs as a single
unit. Each pair is allocated together and starts with a Tx queue and
ends with an Rx queue. By ordering them this way it is possible to know
the Rx offset based on a pointer to the Tx queue.

Allocate the q_vectors individually. The advantage to this is that it
allows for easier freeing and allocation. In addition it makes it so
that we could do node specific allocations at some point in the future.
