9352c19f63 mac80211: extend get_tkip_seq to all keys
Extend the function to read the TKIP IV32/IV16 to read the IV/PN for
all ciphers in order to allow drivers with full hardware crypto to
properly support this.

01fbd4ecff rt2800usb: check Autorun mode on FW load only once
Seems H/W report correctly firmware Autorun value only at initialization
stage. When we close interface and open it again, Autorun value is 0 and
we try to load firmware what kills the device. To fix clear
REQUIRE_FIRMWARE firmware flag, to do not load firmware again, once we
discover Autorun mode.

2c4db12ec4 rt2800usb: Don't perform DMA from stack
Function rt2800usb_autorun_detect() passes the address of a variable
allocated onto the stack to be used for DMA by the USB layer. This has
been caught by my debugging-enabled kernel.

This patch change things in order to allocate that variable via
kmalloc, and it adjusts things to handle the kmalloc failure case,
propagating the error.

b663cd10f0 rt2800usb:fix hang during firmware load
The device 057c:8501 (AVM Fritz! WLAN v2 rev. B) boots into a state that does
not actually require loading a firmware file. The vendors driver finds out
about this by checking a firmware state register, so this patch adds this here.

Finally, with this patch applied, my wifi dongle actually becomes
useful (scan + connect to wpa network works).

de51b35d50 rt2800usb:fix efuse detection
The device 057c:8501 (AVM Fritz! WLAN v2 rev. B) currently does not
load. One thing observed is that the vendors driver detects EFUSE mode
for this device, but rt2800usb does not. This is due to rt2800usb
lacking a check for the firmware mode present in the vendors driver,
that this patch adopts for rt2800usb.

With this patch applied, the 'RF chipset' detection does no longer fail.

434bb46c36 wireless/rt2x00: don't use PREPARE_WORK in rt2800usb.c
PREPARE_[DELAYED_]WORK() are being phased out.  They have few users
and a nasty surprise in terms of reentrancy guarantee as workqueue
considers work items to be different if they don't have the same work
function.

Update rt2800usb.c to use INIT_WORK() instead of PREPARE_WORK().  As
the work item isn't in active use during rt2800usb_probe_hw(), this
doesn't cause any behavior difference.

It would probably be best to route this with other related updates
through the workqueue tree.

Only compile tested.

498d319bb5 kfifo API type safety
This patch enhances the type safety for the kfifo API.  It is now safe
to put const data into a non const FIFO and the API will now generate a
compiler warning when reading from the fifo where the destination
address is pointing to a const variable.

As a side effect the kfifo_put() does now expect the value of an element
instead a pointer to the element.  This was suggested Russell King.  It
make the handling of the kfifo_put easier since there is no need to
create a helper variable for getting the address of a pointer or to pass
integers of different sizes.

IMHO the API break is okay, since there are currently only six users of
kfifo_put().

The code is also cleaner by kicking out the "if (0)" expressions.

36165fd5b0 rt2800usb: slow down TX status polling
Polling TX statuses too frequently has two negative effects. First is
randomly peek CPU usage, causing overall system functioning delays.
Second bad effect is that device is not able to fill TX statuses in
H/W register on some workloads and we get lot of timeouts like below:

ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2
ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2
ieee80211 phy4: rt2800usb_txdone: Warning - Got TX status for an empty queue 2, dropping

This not only cause flood of messages in dmesg, but also bad throughput,
since rate scaling algorithm can not work optimally.

In the future, we should probably make polling interval be adjusted
automatically, but for now just increase values, this make mentioned
problems gone.

ae1b1c5dcd rt2x00: rt2800lib: introduce rt2800_get_txwi_rxwi_size helper
The rt2800pci driver uses the same [RT]XWI size
for all chipsets, however some chips requires
different values.

The size of the [RT]XWI structures is a constant
value for a given chipset and it does not depend
on the underlying interface. Add a helper function
which returns the correct values for the actual
chipset and use the new helper both in the rt2800usb
and in the rt2800pci drivers. This ensures that both
drivers are using the correct values.

d02433d155 rt2x00: rt2800usb: add USB device ID for Linksys AE3000
The Linksys AE3000 device is based on the RT3573
chipset. The support for this chipset is available
already, and the AE3000 device works with the driver.

Only managed mode works correctly at the moment,
for AP mode additional changes are needed in the
driver.

Also add a new RT2800USB_RT3573 Kconfig option and
only enable support for RT3573 based devices if
that is enabled.

The extra_tx_headroom field of struct rt2x00_ops
indicates the extra TX headroom size required for
a given device. This data is redundant, the value
can be computed from the desc_size and winfo_size
fields of the TX queues.

Move the extra_tx_headroom field to struct rt2x00_dev,
compute its value in the probe routine and use the
cached value in the rest of the code.

Remove the static data queue descriptor structures

The actual chipset is already known when the callback
is used. This allows us to use a single callback for

The RX data queue is initialized already when
the rt2800_usb_enable_radio() function is called.

Fetch the number of the queue entries from that
instead of using the entry_num field of the data
queue descriptor.

The two values are the same, and the use of the
rt2x00dev->rx->limit value allows us to get rid
of a superfluous pointer dereference.

f0bda57104 rt2x00: provide separate information about TXWI & RXWI sizes
On new 2800 hardware sizes of TXWI & RXIW can be different than TXD
& RXD sizes, so we need to difference between them. Let's define
winfo_size as size of in buffer descriptor (TXWI & RXWI), and desc_size
of as size of additional descriptor - in separate DMA coherent buffer
for PCI hardware (TXD & RXD) and yet another in buffer descriptor for
USB hardware (TXINFO & RXINFO).

Change is rt2x00 wild, but should affect only 2800 driver.

Patch also fix beaconing for 5592usb AP mode.

D-Link DWA-125/B1 is a relatively new USB Wi-Fi adapter, using a
Ralink chipset supported by the rt2800usb driver. Currently, to work
around the problem (it's missing in all present kernel versions,
up to and including 3.7.x), I had to add this to /etc/rc.local:

echo 2001 3c1e >> /sys/bus/usb/drivers/rt2800usb/new_id

After that, the device works without problems. Been using it for over
a week with no bugs in sight.

The attached patch is trivial and simply adds the new USB ID to the
list of devices handled by rt2800usb.

761ce8c41e rt2x00: usb: fix reset resume
Patch fixes warnings like below happened on resume:

WARNING: at net/mac80211/driver-ops.h:12 check_sdata_in_driver+0x32/0x34()

Problem is that in __ieee80211_susped() we remove sdata (i.e wlan0
interface) and then during resume we call usb_unbind_interface() ->
ieee80211_unregister_hw() with sdata removed.

Patch fixes problem by adding .reset_resume calback, hence we do not
unbind usb device on resume. This callback can be the same as normal
.resume callback, sice we do all needed initalization during interface
start, which is performed on resume [ ieee80211_resume() ->
ieee80211_reconfig() -> rt2x00mac_start() -> rt2x00lib_start ].
