Eliad Peller 18eab43070 wlcore: workaround start_sta problem in wl12xx fw
for some reason, the wl12xx fw is not able to rx/tx
on the first start_sta cmd.
Workaround it by issuing a dummy start_sta + stop_sta
before starting the sta for the final time.

Eliad Peller 3230f35e09 wlcore: start sta role on CHANGED_BSSID
Make the connection flow simpler by starting
sta role on bssid change.

Currently, we start dev role when going idle-off,
and start the sta role only after association
indication. This complicates the connection
flow with some possible intermediate states.

Make it simpler by starting sta role on bssid change,
which now happens *before* auth req get sent.

Update the handling of mac80211's notifications
and change wl1271_join/unjoin accordingly -
* Split wl1271_join() into wlcore_join (tuning on
  a channel/bssid) and wlcore_set_assoc (configure
  sta after association).
* Rename wl1271_unjoin() to wlcore_unset_assoc(), as
  it is no longer the inversion of wl1271_join()
  (now it's only used to disconnect associated sta /
  joined ibss, without stopping the role).
* Set ssid before starting station role (needed for
  start_role(sta)

While on it, split wl1271_bss_info_changed_sta() into
some sub-functions.

since we no longer use dev role in the connection flow,
we now always use the hlid of the sta role.

Wei Yongjun 200e932649 wlcore: sdio: use platform_device_unregister in wl1271_remove()

platform_device_put(), thus use platform_device_unregister() to
simplify the code.

Also the documents in platform.c shows that platform_device_del
and platform_device_put must _only_ be externally called in error
cases.  All other usage is a bug.

Julia Lawall 4fb4e0bee1 drivers/net/wireless/ti/wlcore/main.c: eliminate possible double power off
The function wl12xx_set_power_on is only called twice, once in
wl12xx_chip_wakeup and once in wl12xx_get_hw_info.  On the failure of the
call in wl12xx_chip_wakeup, the containing function just returns, but on
the failure of the call in wl12xx_get_hw_info, the containing function
calls wl1271_power_off.  This does not seem necessary, because if
wl12xx_set_power_on has set the power on and then fails, it has already
turned the power off.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

Set tx packet timestamp to 0 in following scenarios:-
- All packets in STA mode
- Mgmt packets in AP mode
- Eapol packets in AP mode

In STA mode, this field is unused in the firmware. In AP
mode, we should not be expiring mgmt and eapol frames.
Setting timestamp to 0 will ensure that.

Avinash Patil 47411a06c0 mwifiex: add multi-queue support
This patch adds support for multiple TX queues inside mwifiex
driver. Four different queues according to WMM access categories
are defined for each virtual interface. When a packet is
received from netdev for transmission, tx pending count for
particular queue is incremented and if tx pending count has
reached upper water-mark, this queue is stopped instead of
stopping all queues. Similarly when a packet is successfully
transmitted from device, tx pending count is decremented per
queue and if pending count falls below lower water-mark, queue
operations are again resumed. This ensures that not all
tranmission is blocked if traffic with particular TOS value
suddenly increases.

Also wake all queues after association/IBSS_join/uAP_BSS_start
to enable traffic on all queues.

Amitkumar Karwar d31ab3577e mwifiex: add support for SDIO card reset
When command timeout happens due to a bug in firmware/hardware,
the timeout handler just prints some debug information. User is
unable to reload the driver in this case.

Inspired by 9a821f5 "libertas: add sd8686 reset_card support",
this patch adds card reset support for SDIO interface when
command timeout happens. If the SDIO host contoller supports
MMC_POWER_OFF|UP|ON operations, the chip will be reset and the
firmware will be re-downloaded.

Harro Haan 73e6991ad3 add Marvell 88W8688 support to libertas_sdio
This chip is for example used in the GuruPlug.
This patch avoids the following error:
libertas_sdio: failed to load firmware
libertas_sdio: probe of mmc0:0001:1 failed with error -5

The fix is based on code in:
drivers/net/wireless/libertas_uap/uap_sdio_mmc.c

This file can for example be found on the following links:
http://www.xilka.com/sheeva/2.6/2.6.36/2.6.36.2/source/0002-Driver-for-Marvell-Libertas-8688-SDIO-micro-AP-suppo-2.6.35.patch
http://www.downloadsnewit.co.uk/kernel-v3.0.7/

I followed the following wiki to setup a working WiFi client mode
connection on the GuruPlug:

Luis R. Rodriguez 158b42edab carl9170: kill MODULE_VERSION
This is pretty pointless. Lets kill this to stop people from
thinking that its actually used. Maybe we should go on
a crusade and kill this completely from the kernel.
