Linux gives us a function to copy Ethernet MAC addresses, let's use it.

Set appropriate fields in Tx queue configuration virtchnl message
to pf to enable headwb and setup headwb addr.
Then use that info from the VF to set headwb and headwb_addr instead of
always enabling them.

Clean up inconsistent log messages, mostly related to punctuation. Based
on the dogma that "kernel messages are not sentences", remove all
trailing periods. Reword a few of the messages to make them less
sentence-like.

We don't need to print log messages when we encounter an out-of-memory
condition, as the allocator will do this for us. Also, remove a Tx hang
message that duplicates the one emitted by the netdev layer, and a
duplicate message in the watchdog.

The rx_errors (GLV_REPC) and rx_missed (GLV_RMPC) were removed
from the chip design.

If the kernel watchdog bites us, ask the PF to reset us and attempt to
reinit the driver.

Respond better to a VF reset event. When a reset is signaled by the
PF, or detected by the watchdog task, prevent the watchdog from
processing admin queue requests, and schedule the reset task.
In the reset task, wait first for the reset to start, then for it to
complete, then reinit the driver.
If the reset never appears to complete after a long, long time (>10
seconds is possible depending on what's going on with the PF driver),
then set a flag to indicate that PF communications have failed.
If this flag is set, check for the reset to complete in the watchdog,
and attempt to do a full reinitialization of the driver from scratch.
With these changes the VF driver correctly handles a PF reset event
while running on bare metal, or in a VM.
Also update copyrights.

This PCI-E SR-IOV virtual function (VF) driver is dependant upon the
physical function (PF) driver (i40e) for nearly all of its hardware
configuration. Requests from the VF driver are passed to the PF using
the hardware's Admin Queue.
This patch contains the functionality for communicating with the PF
driver. Because of the delay inherent in this communications channel,
most of the replies from the PF driver are handled asynchronously. The
exceptions are the "send API version" and "get VF config" messages,
which busy-wait because they are done so early during init that
interrupts are not yet configured.
