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.

The PF reset to clean up at the end of the remove is a nice thing
to do, but it also removes any LAA setting that Wake On LAN wants
for future wake up.

Don't short-circuit the LAA assignment when the driver thinks it has
already been done - it is possible that the user might want to force
the address setting again.  At the same time, this requires a little
re-ordering of the filter management.

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.

Using napi infrastructure to move the tx clean up out of isr to softirq.
Now, wq isr schedules napi poll. In enic_poll_msix_wq we clean up the tx queus.

This is applicable only on MSIX. In INTx and MSI we use single napi to clean
both rx & tx queues.

This patch adds support for low latency busy_poll.

* Introduce drivers ndo_busy_poll function enic_busy_poll, which is called by
socket waiting for data.

* Introduce locking between napi_poll nad busy_poll

* enic_busy_poll cleans up all the rx pkts possible. While in busy_poll, rq
holds the state ENIC_POLL_STATE_POLL. While in napi_poll, rq holds the state
ENIC_POLL_STATE_NAPI.

* in napi_poll we return if we are in busy_poll. Incase of INTx & msix, we just
service wq and return if busy_poll is going on.

This patch adds supports for Accelerated Receive Flow Steering.

When the desired rx is different from current rq, for a flow, kernel calls the
driver function enic_rx_flow_steer(). enic_rx_flow_steer adds a IP-TCP/UDP
hardware filter.

Driver registers a timer function enic_flow_may_expire. This function is called
every HZ/4 seconds. In this function we check if the added filter has expired
by calling rps_may_expire_flow(). If the flow has expired, it removes the hw
filter.

As of now adaptor supports only IPv4 - TCP/UDP filters.
