To make get/set netlink VF_PORT truly symmetrical, we need to keep track
of what items are set and only return those items on get. Previously, the
driver wasn't differentiating between a set of attr with a NULL string,
for example, and not setting the attr at all. We only want to return
the NULL string if the attr was actually set with a NULL string. Otherwise,
don't return the attr.

bnx2: Fix netpoll crash.
If ->open() and ->close() are called multiple times, the same napi structs
will be added to dev->napi_list multiple times, corrupting the dev->napi_list.
This causes free_netdev() to hang during rmmod.
We fix this by calling netif_napi_del() during ->close().
Also, bnx2_init_napi() must not be in the __devinit section since it is

Following changes have been added to enable the adapter to work in
NIC partitioning mode where multiple PCI functions of an adapter port can
be configured to work as NIC functions. The first function that is enumerated on
the PCI bus assumes the role of management function which, besides being able
to do all the NIC functionality, can configure other NIC partitions. Other NIC
functions can be configured as privileged or non privileged functions.
Privileged function can not configure other NIC functions but can do all the
NIC functionality including any firmware initialization, chip reset etc. Non
privileged functions can do only basic IO. For chip reset etc, it depends on the
privilege or management function.
1. Added code to determine PCI function number independent of kernel API.
2. Added Driver - FW version 2.0 support.
3. Changed producer and consumer register offset calculation.
4. Added management and privileged operation modes for npar functions. A module
parameter has been added to control it.
5. Added support for configuring the eswitch in the adapter.

A single shared memory region used to communicate with firmware is
mapped into both PCI PFs of the SFC9020 and SFL9021. Drivers must be
able to identify which port they are addressing in order to use the
correct sub-region. Currently we use the PCI function number, but the
PCI address may be virtualised. Use the CS_PORT_NUM register field
defined for just this purpose.

Insert a structure at the start of the shared page that
tracks the dma mapping refcnt. DMA into the next cache
line of the (shared) page (plus EFX_PAGE_IP_ALIGN).
When recycling a page, check the page refcnt. If the
page is otherwise unused, then resurrect the other
receive buffer that previously referenced the page.
Be careful not to overflow the receive ring, since we
can now resurrect n receive buffers in a row.

The cut-through design of the receive path means that packets that
fail to match the appropriate MAC filter are not discarded at the MAC
but are flagged in the completion event as 'to be discarded'. On
networks with heavy multicast traffic, this can account for a
significant proportion of received packets, so it is worthwhile to
recycle the buffer immediately in this case rather than freeing it
and then reallocating it shortly after.
The only complication here is dealing with a page shared
between two receive buffers. In that case, we need to be
careful to free the dma mapping when both buffers have
been free'd by the kernel. This means that we can only
recycle such a page if both receive buffers are discarded.
Unfortunately, in an environment with 1500mtu,
rx_alloc_method=PAGE, and a mixture of discarded and
not-discarded frames hitting the same receive queue,
buffer recycling won't always be possible.

Ensure that efx_fast_push_rx_descriptors() must only run
from efx_process_channel() [NAPI], or when napi_disable()
has been executed.
Reimplement the slow fill by sending an event to the
channel, so that NAPI runs, and hanging the subsequent
fast fill off the event handler. Replace the sfc_refill
workqueue and delayed work items with a timer. We do
not need to stop this timer in efx_flush_all() because
it's safe to send the event always; receiving it will
be delayed until NAPI is restarted.

Under certain conditions a PHY may backpressure Falcon B0
in such a way that flushes timeout. In normal circumstances
the phy poller would fix the PHY, and the flush could complete.
But efx_nic_flush_queues() is always called after efx_stop_all(),
so the poller has been stopped. Even if this weren't the case,
how long would we have to wait for the poller to fix this? And
several callers of efx_nic_flush_queues() are about to reset
the device anyway - so we don't need to do anything.
Work around this bug by scheduling a reset. Ensure that the
MAC is never rewired back into the datapath before the reset
runs (we already ignore all rx events anyway).

We can wake all queues after a chip reset since everything should be set up and
we are ready to transmit. If we don't do that we might end up starting up with
stopped queues, not beeing able to transmit. (This started to happen after
"ath5k: clean up queue manipulation" but since periodic calibration also
stopped and started the queues this effect was hidden most of the time).
This way we can also get rid of the superfluous ath5k_reset_wake() function.

Add a spin_unlock missing on the error path. The return value of write_reg
seems to be completely ignored, so it seems that the lock should be
released in every case.
The semantic match that finds this problem is as follows:

// <smpl>

* spin_lock(E1,...);

This patch fixes an occasional transmit lockup in the mac-fcc which
occurs after a tx error. The test scenario had the local port set
to autoneg and the other end fixed at 100FD, resulting in a large
number of late collisions.
According to the MPC8280RM 30.10.1.3 (also 8272RM 29.10.1.3), after
a tx error occurs, TBPTR may sometimes point beyond BDs still marked
as ready. This patch walks back through the BDs and points TBPTR to
the earliest one marked as ready.
Tested on a custom board with a MPC8280.

acpi pad driver kind of aggressively marks TSC as unstable at init
time, on mwait capable and non X86_FEATURE_NONSTOP_TSC systems. This is
irrespective of whether pad driver is ever going to be used on the
system or deep C-states are supported/used. This will affect every user
who just happens to compile in (or get a kernel version which
compiles in) acpi pad driver.
Move mark_tsc_unstable() out of init to the actual idle invocation path
of the pad driver.
There is also another bug/missing_feature in the code that it does not
support 'always running apic timer' and switches to broadcast mode
unconditionally. Shaohua, can you take a look at that please.

This EXPERIMENTAL driver supersedes acpi_idle on
Intel Atom Processors, Intel Core i3/i5/i7 Processors
and associated Intel Xeon processors.
It does not support the Intel Core2 processor or earlier.
For kernels configured with ACPI, CONFIG_INTEL_IDLE=y
allows intel_idle to probe before the ACPI processor driver.
Booting with "intel_idle.max_cstate=0" disables intel_idle
and the system will fall back on ACPI's "acpi_idle".
Typical Linux distributions load ACPI processor module early,
making CONFIG_INTEL_IDLE=m not easily useful on ACPI platforms.
intel_idle probes all processors at module_init time.
Processors that are hot-added later will be limited
to using C1 in idle.

commit d306ebc286
(ACPI: Be in TS_POLLING state during mwait based C-state entry)
fixed an important power & performance issue where ACPI c2 and c3 C-states
were clearing TS_POLLING even when using MWAIT (ACPI_STATE_FFH).
That bug had been causing us to receive redundant scheduling interrups
when we had already been woken up by MONITOR/MWAIT.
Following up on that...
In the MWAIT case, we don't have to subsequently
check need_resched(), as that c heck was there
for the TS_POLLING-clearing case.
Note that not only does the cpuidle calling function
already check need_resched() before calling us, the
low-level entry into monitor/mwait calls it twice --
guaranteeing that a write to the trigger address
can not go un-noticed.
Also, in this case, we don't have to set TS_POLLING
when we wake, because we never cleared it.

ath9k: Remove ATH9K_TX_SW_ABORTED and introduce a bool for this purpose
Wrong buffer is checked for bf_tx_aborted field in ath_tx_num_badfrms(),
this may result in a rate scaling with wrong feedback (number
of unacked frames in this case). It is the last one in the chain
of buffers for an aggregate frame that should be checked.
Also it misses the initialization of this field in the buffer,
this may lead to a situation where we stop the sw retransmission
of failed subframes associated to this buffer.
