With the auto_disable flags added there was a bug that was causing the
replay logic to not work correctly.
This patch fixes the issue so that we call a replay after a sideband
reset correctly.

Per a recent HW designer comment, this code is for ripping through the
queues and interrupts to fully disable them on driver init, specifically
to help clean up after a PXE or other early boot activity.

Hardware does not have a way of telling a PF how much of the global
shared FD table space is still available or is consumed.
Previously, every PF but PF0 would think there was still space available
when there wasn't. The PFs would continue to try to add filters and fail.
With this new logic if a filter programming error is detected we just
check if we are close to the guaranteed space full and that can be used
as a hint to say, there might not be space and we should turn off the
features. This way we can turn off the feature in SW for all PFs in
time.

There wasn't a need to play the logic twice, it seems
like a left over from when we had to add two PTYPEs for
one filter. There should be no change in the number of
filters that actually got added to the hardware.

Currently every time we run through the i40e_ptp_init routine, we create
a new device node. This function is called by i40e_reset_and_rebuild
which is used to handle reset of the device. Even though the 1588
registers only get cleared on a GLOBAL reset, this function is still
called to handle a CORE reset.
This causes a leak of PTP device nodes at every reset. To fix this,
break PTP device clock node creation out of i40e_ptp_init, and only call
this if we don't already have a device created. Further invocation of
i40e_ptp_init will not generate new PTP devices. Instead, only the
necessary work required to reconfigure 1588 will be done.
This change also fixes an issue where a reset can cause the
device to forget it's timestamp configuration, and revert to the default
mode.

This patch facilitates future work by breaking the PTP hardware control
bits out of the i40e_set_ts_config function. By doing this, we can
maintain state about the 1588 timestamping mode and properly re-enable
to the last known mode during a re-initialize of 1588 bits.
This patch also modifies i40e_ptp_init to call the
i40e_ptp_set_timestamp_mode during the reconfiguration process. A
future patch will ensure that the hwtstamp_config structure is not reset
during this process, so that timestamp mode will be maintained across a
reset.

When a Tx hang happens, usually the Tx queue disable fails. At
this point if we try to recover by a VSI reinit the HW gets
unhappy and we get a Malicious Driver Detect (MDD) event.
HW expects a PF reset if a queue disable fails, if we don't do a PF
reset and restart the queue we get an MDD. This patch makes sure we
do a PF reset on Tx hang and that way we avoid any MDD because of Tx
queue disable failure.

As per the spec when the PF driver receives a Malicious driver event
the queue that caused the event is already stopped and it is expected
that the function that owns the queue will reset the queue.
In some cases it may not be possible to determine the queue and it is
suggested to reset the whole function.
This patch takes the later approach when the event is owned by the PF
that owns it.

The return from i40e_prep_for_reset() was being ignored by almost all
its callers. The one place it wasn't ignored could have caused a silent
and confusing failure of the driver to finish a reset. Since we really
are doing a rebuild anyway, ignore this last case as well and simply
make the function a void type.

If the host VMM administrator has changed the VF device's MAC address then
the i40e driver needs to halt the VF device so that the administrator will
be forced to reload the VF driver. This will cause the VF driver to start
using the newly assigned MAC address. This brings the i40e driver into
conformance with operational characteristics of other Intel SR-IOV
featured drivers.
