transmits while we're shutting down. Additionally, disable NAPI before
disabling interrupts, or the interrupt might get re-enabled
inappropriately. Finally, remove the call to netif_tx_stop_all_queues,

When the VF interface is closed, we cannot immediately free our rings
and RX buffers, because the hardware hasn't yet stopped accessing this
memory. This shows up as a panic or memory corruption when the device is
brought down while under heavy stress.
To fix this, delay releasing resources until we receive acknowledgment
from the PF driver that the rings have indeed been stopped. Because of
this delay, we also need to check to make sure that all of our admin
queue requests have been handled before allowing the device to be
opened.

Under rare circumstances, after a reset, set_rx_mode might get called
while the watchdog is running, which will cause a deadlock on the
critical section lock. To correct this, add a counter and give up trying
to get the lock after fifty tries. Log a message if this happens but
don't take any other action. Because this happens after a reset, all of
the Rx filters are still in place and the device won't lose
connectivity.
We can also get stuck during shutdown, if the PF has stopped communicating
with us, or if a reset is occurring. If we can't get the lock after a reasonable
amount of time, just error out. Something else bad is happening anyway, so
adding this filter is the least of our concern right now.

A recent change to the shutdown flow messed up the reset flow. Since
i40evf_down now holds the critical section lock, we cannot call it from
the reset handler, which also holds the lock. To do so causes a deadlock
accompanied by wailing and gnashing of teeth. This is easily triggered
by running an ethtool self-test on the PF device.
Instead, we move the relevant portions of i40evf_down into the reset
handler and bend them to our will. Additionally, we can optimize the
reinit path by not deleting the MAC and VLAN filters and then adding
them back again. Instead, we just set the 'add' flag and let the
watchdog resynchronize the filter list with the PF driver. We also
reword a few messages to make them more consistent with the rest of the
driver.

Split the receive hot path code into two, one for packet split and one
for single buffer. This improves receive performance since we only need
to check if the ring is in packet split mode once per NAPI poll time,
not several times per packet. The single buffer code is further improved
by the removal of a bunch of code and several variables that are not
needed. On a receive-oriented test this can improve single-threaded
throughput.
Also refactor the packet split receive path to use a fixed buffer for
headers, like ixgbe does. This vastly reduces the number of DMA mappings
and unmappings we need to do, allowing for much better performance in
the presence of an IOMMU.
Lastly, correct packet split descriptor types now that we are actually
using them.

When the module is being unloaded, don't wait for the PF to politely

When the original shutdown code was written, VF resets were unreliable,

On some versions of the firmware, the VF admin send queue may become
stalled. In this case, the easiest solution is to just place another
descriptor on the queue; the firmware will then process both requests.
The early init code already accounts for this, but the runtime code does
not. In the watchdog task, check for the stall condition, and if it's
found, send our API version to the PF. When the PF replies, just ignore
the reply.

There is always a possibility that MSI-X interrupts can get lost. To
keep this problem from stalling the driver, we fire all of our MSI-X
vectors during the watchdog routine. However, we should not fire the
traffic vectors when the interface is closed. In this case, just fire
vector 0, which is used for admin queue events.
As a result, we do not enable the interrupt cause for vector 0. This
can cause the admin queue handler to be called reentrantly, which
causes a scary "critical section violation" message to be logged,
even though no real damage is done.

When multiple VFs attempt to initialize simultaneously, the firmware may
delay or drop messages. Make the init code more adept at handling these
situations by a) reinitializing the admin queue if the firmware fails to
process a request, and b) resending a request if the PF doesn't answer.
Once the request has been sent again, the PF might end up getting both
requests and send the configuration information to the driver twice.
This will cause the VF to complain about receiving an unexpected message
from the PF. Since this is not fatal, reduce the warning level of the
log messages that are generated in response to this event.

Overloading the msg_size field in the arq_event_info struct is just a
bad idea. It leads to repeated bugs when the structure is used in a
loop, since the input value (buffer size) is overwritten by the output
value (actual message length).
Fix this by splitting the field into two and renaming to indicate the
actual function of each field.
Since the arq_event struct has now changed, we need to change the drivers
to support this. Note that we no longer need to initialize the buffer size
each time we go through a loop as this value is no longer destroyed by
arq processing.
In the process, we also fix a bug in i40evf_verify_api_ver where the
buffer size was not correctly reinitialized each time through the loop.

Previously defined state I40E_VFR_VFACTIVE uses bit 1 which is now set to
"reserved." Update the state checks to also include I40E_VFR_COMPLETED.
This change will allow the VF to work with both existing and future PFs.

The driver was converted to use snprintf everywhere but this one function.
Just use snprintf, instead of sprintf.
Also a small spelling correction in a comment.
