The rt2800 specific code contains a lots of whitespace damage caused by
the commit 'rt2x00: Add support for RT5390 chip'.
This patch fixes those whitespace errors.

The driver for the RTL8187L chips returns IEEE80211_TX_STAT_ACK for all
packets, even if the maximum number of retries was exhausted. In addition
it fails to setup max_rates in the ieee80211_hw struct, This behavior
may be responsible for the problems noted in Bug 14168. As the bug is very
old, testers have not been found, and I do not have the case where the
indicated signal is less than -70 dBm.

TX might be handled in the threaded IRQ handler, in which case, TX work
might be scheduled just to discover it has nothing to do.
Save a few context switches by cancelling redundant TX work in case TX
is about to be handled in the threaded IRQ handler. Also, avoid
scheduling TX work from wl1271_op_tx if not needed.

The interrupt of the wl12xx is a level interrupt in nature, since the
interrupt line is not auto-reset. However, since resetting the interrupt
requires bus transactions, this cannot be done from an interrupt
context. Thus, requesting a level interrupt would require to disable the
irq and re-enable it after the HW is acknowledged. Since we now request
a threaded irq, this can also be done by specifying the IRQF_ONESHOT
flag.
Triggering on an edge can be problematic in some platforms, if the
sampling frequency is not sufficient for detecting very frequent
interrupts. In case an interrupt is missed, the driver will hang as the
interrupt line will stay high until it is acknowledged by the driver,
which will never happen.
Fix this by requesting a level triggered interrupt, with the
IRQF_ONESHOT flag.

To achieve maximal throughput, it is very important to react to
interrupts as soon as possible. Currently the interrupt handler wakes up
a worker for handling interrupts in process context. A cleaner and more
efficient design would be to request a threaded interrupt handler. This
handler's priority is very high, and can do blocking operations such as
SDIO/SPI transactions.
Some work can be deferred, mostly calls to mac80211 APIs
(ieee80211_rx_ni and ieee80211_tx_status). By deferring such work to a
different worker, we can keep the irq handler thread more I/O
responsive. In addition, on multi-core systems the two threads can be
scheduled on different cores, which will improve overall performance.
The use of WL1271_FLAG_IRQ_PENDING & WL1271_FLAG_IRQ_RUNNING was
changed. For simplicity, always query the FW for more pending
interrupts. Since there are relatively long bursts of interrupts, the
extra FW status read overhead is negligible. In addition, this enables
registering the IRQ handler with the ONESHOT option.

The SDIO bus is claimed and released for each SDIO transaction. In
addition to the few CPU cycles it takes to claim and release the bus, it
may also cause undesired side effects such as the MMC host stopping its
internal clocks.
Since only the wl12xx_sdio driver drives this SDIO card, it is safe to
claim the SDIO host once (on power on), and release it only when turning
the power off.
This patch was inspired by Juuso Oikarinen's (juuso.oikarinen@nokia.com)
patch "wl12xx: Change claiming of the (SDIO) bus".

On newer hardware revisions, there is no need to write the host's
counter at the end of a RX transaction. The same applies to writing the
number of packets at the end of a TX transaction.
It is generally a good idea to avoid unnecessary SDIO/SPI transfers.
Throughput and CPU usage are improved when avoiding these.
Send the host's RX counter and the TX packet count only if needed, based
on the hardware revision.

The FW has a limited amount of memory for holding frames. In case it
runs out of memory reserved for RX frames, it'll have no other choice
but to drop packets received from the AP. Thus, it is important to
handle RX data interrupts as soon as possible, before handling anything
else.
In addition, since there are enough TX descriptors to go around, it is
better to first send TX frames, and only then handle TX completions.
Fix this by changing the order of function calls in wl1271_irq_work.

Frames in the tx_frames array include extra private headers, which must

Fix this by removing any private headers in wl1271_tx_reset, similar to
how this is done in wl1271_tx_complete_packet.

Runtime PM might not always be enabled. Even if it is enabled in the
running kernel, it can still be temporarily disabled, for instance
during suspend. Runtime PM is opportunistic in nature, and should not be
relied on for toggling power.
In case the interface is removed and re-added while runtime PM is
disabled, the FW will fail to boot, as it is mandatory to toggle power
between boots. For instance, this can happen during suspend in case one
of the devices fails to suspend before the MMC host suspends, but after
mac80211 was suspended. The interface will be removed and reactivated
without toggling the power.
Fix this by calling mmc_power_save_host/mmc_power_restore_host in
wl1271_sdio_power_on/off functions. It will toggle the power to the chip
even if runtime PM is disabled. The runtime PM functions should still be
called to make sure runtime PM does not opportunistically power the chip
off (e.g. after resuming from system suspend).

Since commit commit 470058e0ad82fcfaaffd57307d8bf8c094e8e9d7
"iwlwifi: avoid Tx queue memory allocation in interface down" we do
not unmap dma and free skbs when down device and there is pending
transfer. What in consequence may cause that system hung (waiting
for free skb's) when performing shutdown at iptables module unload.
DMA leak manifest itself following warning:

I still can observe above warning after apply patch, but it is very
hard to reproduce it, and have count=1. Whereas that one is easy to
reproduce using debugfs force_reset while transmitting data, and have
very big counts eg. 240, like quoted here. So count=1 WARNING seems
to be different issue that need to be resolved separately.
v1 -> v2: fix infinity loop bug I made during "for" to "while" loop transition.
v2 -> v3: remove unneeded EXPORT_SYMBOL

rate_mask is initialized again later so this can be removed. Btw, if
rate_control_send_low(sta, priv_sta, txrc) returns false, that means
that "sta" is non-NULL. That's why the second initialization of
rate_mask is a little simpler than the first.

This patch fixes tramissing on OFDM rates for PHYs 1 and 2. There is
still something wrong with PHYs 3+. Tests has shown decreasing of
performance on CCK rates by 1-2%, we have to live with that.
Additionaly this noticeably reduces amount of PHY errors. They were
mostly produced by auto-switching to higher rate for better
performanced, which resulted in no transmit at all and PHY errors.
