Stanislaw Gruszka c1de4a9557 iwl4965: better skb management in rx path
4965 version of Eric patch "iwl3945: better skb management in rx path".
It fixes several problems :

1) skb->truesize is underestimated.
   We really consume PAGE_SIZE bytes for a fragment,
   not the frame length.
2) 128 bytes of initial headroom is a bit low and forces reallocations.
3) We can avoid consuming a full page for small enough frames.

Avinash Patil 78dfca62f1 mwifiex: populate rates in probe request using cfg80211_scan_request
Whenever available, use cfg80211_scan_request to populates rates
in outgoing probe request. This will help to advertise band specific
rates and fix an issue where 11b rates were advertised in probe
request going out on 11a band.

This will also ensure that we do not advertise 11b rates while P2P
scan is going on.

Amitkumar Karwar c3afd99fb5 mwifiex: fix adapter pointer dereference issue
It has introduced by recent commit 6b41f941d7cd: "mwifiex:
handle driver initialization error paths" which adds error
path handling for mwifiex_fw_dpc().

release_firmware(adapter->*) is called for success as well
as failure paths. In failure paths, adapter is already freed
at this point.

The issue is fixed by moving mwifiex_free_adapter() call.

Amitkumar Karwar 6b41f941d7 mwifiex: handle driver initialization error paths
mwifiex_fw_dpc() asynchronously takes care of firmware download
and initialization. Currently the error paths in mwifiex_fw_dpc()
are not handled. So if wrong firmware is downloaded, required
cleanup work is not performed. memory is leaked and workqueue
remains unterminated in this case.

mwifiex_terminate_workqueue() is moved to avoid forward
declaration.

Hauke Mehrtens 72bb2f2678 bgmac: make bgmac depend on bcm47xx
bgmac uses bcm47xx_nvram.h which is only available when BCM47XX was
selected. Earlier BCMA_HOST_SOC depended on BCM47XX so this was not
build on any other archs, but that changed. We should modify this
driver to get access to the nvram or the variables through platform
data.

This fixes a build problem in linux-next reported by Stephen Rothwell:

Since the diversity combining macros are common to all chip

Amitkumar Karwar bedb361b50 mwifiex: correction in mwifiex_check_fw_status() return status
For PCIe cards, when wrong firmware is downloaded, firmware is
failed to be ready in 10 seconds. We should return an error at
this point. But currently we are sending first command to firmware.
As expected firmware doesn't respond to this command and command
timeout occurs.

variable modifications in "if (ret) {" block.

After downloading the firmware, firmware status is checked by
reading a register. Polling interval is 100 msecs. Therefore 100
retries means the status is checked for 10 secs which is more than
sufficient for firmware to get ready.

This patch removes 1000 retries macro usage, because 100secs
time is not practical.

Clear the data pointer stored in USB interface structure in
this handler. This helps to return from mwifiex_usb_disconnect()
if driver deinitialization is already performed while handling
an error path for mwifiex_usb_probe().

USB8797 card gets enumerated twice. First enumeration is for
firmware download and second enumeration expects firmware
initialization. mwifiex_usb_probe() always takes care of
deinitialization for first enumeration after firmware download.

Also, this change matches our handling for SDIO and PCIe
interfaces.

Vladimir Kondratiev 6cdadd4dc7 wil6210: fix subtle race in wil_tx_vring
Finish all SW context modifications prior to notifying hardware

It used to be race condition: if HW finish Tx and issue Tx completion IRQ very fast,
prior to SW context update in wil_tx_vring, Tx completion will mis-handle descriptor, as
SW part will have no skb pointer stored.

Vladimir Kondratiev f88f113a54 wil6210: Introduce struct for sw context
Enable adding more data to the SW context.
For now, add flag "mapped_as_page", to separate decisions on free-ing skb
and type of DMA mapping.
This allows linking skb itself to any descriptor of fragmented skb.

No need to modify HW descriptor, as it will be re-initialized on Tx.

Vladimir Kondratiev 4d1ac0721a wil6210: fix wrong index in wil_vring_free
When destroying Rx vring, branch for Rx used wrong Tx descriptor:
while SW context was taken for "head", HW descriptor was, by mistake,
taken from "tail"

Gabor Juhos 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 RT3593 chipset requires different [RT]XWI size
values. Modify the driver to use the correct values.
