fec_suspend() calls fec_stop() to stop the transmit ring while the
transmit packet processing is still active. This can lead to the
transmit queue being restarted by an intervening packet queued for
transmission, or by the tx quirk timer expiring.
Fix this by disabling NAPI first, which will ensure that the NAPI
handlers are not running. Then, take the transmit lock before
detaching the netif device. This ensures that there are no races
with the transmit path - and also ensures that the watchdog won't
fire.
We can then safely stop the ethernet device itself, knowing that the
rest of the driver is safely shut down.
On resume, we bring the device back up in reverse order - we restart
the device, reattach the device (under the tx lock), and then enable
the NAPI handlers.
We also need to adjust the close function to cope with this new
sequence, so that it's possible to cleanly close down the driver
after the hardware fails to resume (eg, due to the regulator_enable()
or pinctrl calls in the resume path returning an error.)

This is the second stage to "move calls to quiesce/resume packet
processing out of fec_restart()", where we remove calls which are not
appropriate to the call site.
In the majority of cases, there is no need to detach and reattach the
interface as we are holding the queue xmit lock across the reset. The
exception to that is in fec_resume(), where we are already detached by
the suspend function. Here, we can remove the call to detach the
interface.
We also do not need to stop the transmit queue. Holding the xmit lock
is enough to ensure that the transmit packet processing is not running
while we perform our task. However, since fec_restart() always cleans
the rings, we call netif_wake_queue() (or netif_device_attach() in the
case of resume) just before dropping the xmit lock. This prevents the
watchdog firing.
Lastly, always call napi_enable() after the device has been reattached
in the resume path so that we know that the transmit packet processing
is already in an enabled state, so we don't call netif_wake_queue()
while detached.

Avoid calling fec_restart() or fec_stop() while the device is down
or not present (iow suspended.)
Although the ndo_timeout method will only be called if the device is
present and running, we defer this to a work queue. The work queue
can run independently, and so needs to repeat these checks to ensure
that a restart doesn't occur after the device has been taken down or
detached for suspend. In this case, we call fec_restart() in the
resume path, so nothing is lost.
For fec_set_features, we add a call to fec_restart() in fec_enet_open()
to ensure that the hardware is appropriate programmed when the interface
is opened. fec_set_features() call should not occur while we're
suspended, so we don't have to worry about that case.
The adjust_link needs similar treatment - this also is called from a
work queue, which may be run independently after we have taken the
device down and detached it. In this case, we just mark the link
down and take no further action. We will reset things appropriately
once the device is up and running again, at which point we will receive
another adjust_link callback.

In 40GE we can't use the default bw units for set ratelimit (100 Mbps)
since the max is 255*100 Mbps = 25 Gbps (not suited for 40GE), thus we need 1 Gbps units.
But for 10GE 1 Gbps units might be too bruit so we use the following solution.
For user set ratelimit <= 25 Gbps:
use 100 Mbps units * user_ratelimit (* 10).
For user set ratelimit > 25 Gbps:
use 1 Gbps units * user_ratelimit.
For user set unlimited ratelimit (0 Gbps):
use 1 Gbps units * MAX_RATELIMIT_DEFAULT (57)
Note: any value > 58 will damage the FW ratelimit computation, so we allow
a max and any higher value will be pulled down to 57.

Intel Wired LAN Driver Updates 2014-07-02
This series contains updates to i40e and i40evf.
Anjali fixes a possible race where we were trying to free the dummy packet
buffer in the function that created it, so cleanup the dummy packet buffer
in i40e_clean_tx_ring() instead. Also fixes an issue where the filter
program routine was not checking if there were descriptors available for
programming a filter.
Mitch fixes unnecessary delays when sending the admin queue commands by
moving a declaration up one level so we do not dereference it out of scope.
Fixes an issue with the VF where if the admin queue interrupts get lost for
some reason, the VF communication will stall as the VFs have no way of
reaching the PF. To alleviate this condition, go ahead and check the ARQ
every time we run the service task. Updates i40evf to allow the watchdog
to fire vector 0 via software, which makes the driver tolerant of dropped
interrupts on that vector.
Paul fixes a shifted '1' to be unsigned to avoid shifting a signed integer.
Jesse disables TPH by default since it is currently not enabled in the
current hardware. Also finishes the i40e implementation of get_settings
for ethtool.
Catherine adds a new variable (hw.phy.link_info.an_enabled) to track whether
auto-negotiation is enabled, along with the functionality to update the
variable. Adds the functionality to set the requested flow control mode.

Allocate, and then map the receive skb before writing any data to the

entries, unmap and free the skb, and then clear the stored skb pointer.
This means we have ring data and skb pointer in one of two states:
either both fully setup, or nothing setup.
This simplifies the cleanup, as we can use just the skb pointer to
indicate whether the descriptor is setup, and thus avoids potentially
calling dma_unmap_single() on a DMA error value.

When the network interface goes down, stop the phy to prevent further

This prevents further reception of link up events which could
potentially call fec_restart().
Since phy_stop() takes the mutex which adjust_link() runs under, we
also ensure that adjust_link() will not already be processing a link
up event.
We also need to do this when suspending as well - we don't want a

sufficient to achieve that - it merely sets a flag to indicate that the

netif_tx_disable() gives this guarantee, since it takes the transmit

While running: while :; do iperf -c <HOST> -P 4; done, transmit timeouts
are regularly reported. With the tx ring dumping in place, we can see
that all entries are in use, and the hardware has finished transmitting
these packets. However, the driver has not reclaimed these ring
entries.
This can occur if the interrupt handler is invoked at the wrong moment -
eg:
CPU0 CPU1
fec_enet_tx()
interrupt, IEVENT = FEC_ENET_TXF
FEC_ENET_TXF cleared
napi_schedule_prep()
napi_complete()
The result is that we clear the transmit interrupt, but we don't trigger
any cleaning of the transmit ring. Instead, use a different strategy:
- When receiving a transmit or receive interrupt, disable both tx and rx
interrupts, but do not acknowledge them. Schedule a napi poll. Don't
loop.
- When we are polled, read IEVENT, acknowledging the pending transmit
and receive interrupts, before then going on to process the
appropriate rings.
This allows us to avoid the race, and has a number of other advantages:
- we cut down on the number of transmit interrupts we have to process.
- we only look at the rings which have pending events.
- we gain additional throughput: the iperf total bandwidth increases
from about 180Mbps to 240Mbps:
