We believe that our earlier patch for supporting multiple hardware
receive queues per enic device requires more internal testing. At this
point, we think that it's best to disable the use of multiple receive
queues. The current patch provides an effective means for the same.

Also, we continue to disallow multiple hardware transmit queues per
device. But change the way we enforce this in order to maintain
consistency with the way receive queues are handled.

This patch re-enables UIE timer/polling emulation for rtc devices

Uwe pointed out that my alarm based UIE emulation is not sufficient
to replace the older timer/polling based UIE emulation on devices
where there is no alarm irq. This causes rtc devices without alarms
to return -EINVAL to UIE ioctls. The fix is to re-instate the old
timer/polling method for devices without alarm irqs.

This patch reverts the following commits:
042620a0 - Remove UIE emulation
1daeddd5 - Cleanup removed UIE emulation declaration
b5cc8ca1 - Remove Kconfig symbol for UIE emulation

The emulation mode will still need to be wired-in with a following
patch before it will work.

On hardware that doesn't support alarm interrupts, rtc_alarm_irq_enable
could return without releasing the ops_lock mutex.

This was introduced in
	aa0be0f4 (RTC: Propagate error handling via rtc_timer_enqueue properly)

This patch corrects the issue by only returning once the mutex is
released.

If management firmware is present and the device is down, the firmware
will assume control of the phy.  If a phy access were allowed from the
host, it will collide with firmware phy accesses, resulting in
unpredictable behavior.  This patch fixes the problem by disallowing phy
accesses during the problematic condition.

Without calling of netif_carrier_off at the end of the probe the operstate
is unknown when the device is initially opened. By default the carrier is
on so when the device is opened and netif_carrier_on is called the link
watch event is not fired and operstate remains zero (unknown).

This patch fixes this behavior in forcedeth and r8169.

There is a double completion associated with error handling for RC QPs.

The sequence is:

 - The do_rc_ack() routine fields an RNR nack and there are 0
   rnr_retries configured on the QP.
 - qib_error_qp() stops the pending timer
 - qib_rc_send_complete() is called from sdma_complete()
 - qib_rc_send_complete() starts the timer because the msb of the psn
   just completed says an ack is needed.
 - a bunch of flushes occur as ipoib posts WQEs to an error'ed QP
 - rc_timeout() calls qib_restart_rc()
 - qib_restart_rc() calls qib_send_complete() with a
   IB_WC_RETRY_EXC_ERR on a wqe that has already been completed in the
   past

The fix avoids starting the timer since another packet will never
arrive.

For each channel, track how many RFS filters are being added during
processing of received packets and scan the corresponding number of
table entries for filters that may be reclaimed.  Do this in batches
to reduce lock overhead.

only set for 82599, so one should check to be sure that pointer is set

The driver was not flushing all writebacks before unloading, possibly
causing memory to be written by the hardware after the driver had
reinitialized the rings.

This adds missing functionality to flush any pending writebacks and is
called in all spots where descriptors should be completed before the driver

Due to the default case handling the older chipsets, a bunch of the newer
ones ended up having the wrong tiling regs used.  This commit switches the
default case to handle the newest chipsets.

This also makes nv4e touch the "extra" tiling regs.  "nv" doesn't touch
them for C51 but traces of the NVIDIA binary driver show it being done
there.

I couldn't find NV41/NV45 traces to confirm the behaviour there, but an
educated guess was taken at each of them.
