671b96db55 ath10k: do not setup rts/frag thresholds for suspended interfaces
mac80211 calls for rts/frag threshold hooks before
any interface is brought back up again when
resuming.

We would set vdev parameters before given vdev is
created lading to a FW crash.

rts/frag thresholds will be re-set accordingly in
add_interface() hook anyway.

679c54a671 ath10k: setup rts/frag thresholds upon vdev creation
mac80211 configures rts/frag thresholds per-hw not
per-vif. ath10k FW expects those values to be set
per-vdev (i.e. per-vif).

ath10k should now respect rts/frag thresholds set
before a given interface was brought up.

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.

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:

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.

This patch fixes the problem by removing unnecessary 'ret'
variable modifications in "if (ret) {" block.
The block is just supposed to update "adapter->winner" flag.

d00062e318 mwifiex: reduce firmware poll retries
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.

2739a95d70 mwifiex: add unregister_dev handler for usb interface
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.

45fe142cef iwl3945: better skb management in rx path
Steinar reported reallocations of skb->head with IPv6, leading to
a warning in skb_try_coalesce()

It turns out iwl3945 has 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.

1cabf7dba5 bcma: return correct error code when bus scan failed
It is better to return the actual error code than just -1.

6ffdead802 bcma: make it possible to select SoC support without mips
To make it possible to use the SoC host interface with ARM SoCs do not
depend on the MIPS driver any more.

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.

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.
