Albert Herranz 24ea602e18 ssb: Implement SDIO host bus support
Add support for communicating with a Sonics Silicon Backplane through a
SDIO interface, as found in the Nintendo Wii WLAN daughter card.

The Nintendo Wii WLAN card includes a custom Broadcom 4318 chip with
a SDIO host interface.

Michael Buesch cde1b55b43 b43: Fix sparse warning in hw-tkip code
This fixes a sparse warning in the hardware-TKIP code:

drivers/net/wireless/b43/xmit.c:272:18: warning: incorrect type in assignment (different base types)
drivers/net/wireless/b43/xmit.c:272:18:    expected unsigned short [unsigned] [short] <noident>
drivers/net/wireless/b43/xmit.c:272:18:    got restricted unsigned short [usertype] <noident>

The code should work correctly with and without this patch applied.

Michael Buesch b0544eb601 b43: Really disable QoS, if requested
Currently, when QoS-disable is requested, we would leave QoS enabled
in firmware, but only queue frames on one queue.
Change that and also tell firmware about disabled QoS, so it
completely ignores all the QoS parameters. Also don't upload the parameters,
if QoS is disabled.

Ivo van Doorn 4789666e13 rt2x00: Hardcode TX ack timeout and consume time
The calculated values for the ACK timeout and ACK
consume time are different then the values as
used by the Legacy drivers.

After testing from James Ledwith it appeared that
the calculated values caused a high amount of TX
failures, and the values from the Legacy drivers
were the most optimal to prevent TX failure due to
excessive retries.

The symptoms of this problem:
 - Rate control module always falls back to 1Mbs
 - Low throughput when bitrate was fixed

Possible side-effects (not confirmed but highly likely)
 - Problems with DHCP
 - Broken connections due to lack of probe response

This should fix at least:
Kernel bugzilla reports: [13362], [13009], [9273]
Fedora bugzilla reports: [443203]
but possible some additional bugs as well.

Joerg Albert fea6734a0e ath,ar9170: implemented conformance test limit calc. for tx power
apply the conformance test limits (CTL) stored in the eeprom upon
the values calculated for the tx power (ar->power_*).

This is based on the implementation in the vendor driver
(hal/hpmain.c, line 3700 ff.) with one difference:
If any ctl mode isn't found in the eeprom, we fall back to the "lower",
legacy modes (5GHT20,11A or 2GHT20,11G,11B). Otus only did 5GHT20->11A.

Currently CTL are applied for the FCC group only.

Sujith 8813262ea7 ath9k: Fix channelFlags for 2GHZ
CHANNEL_G has to be set for 2GHZ channels since
IS_CHAN_G() checks for this in channelFlags and not in
chanmode. To make things messier, ath9k_hw_process_ini()
checks for CHANNEL_G in chanmode and not in channelFlags.
The supreme, brain-searing fix is to set the
flag in both cases.

David S. Miller 6ec1c69a8f net_sched: add classful multiqueue dummy scheduler
This patch adds a classful dummy scheduler which can be used as root qdisc
for multiqueue devices and exposes each device queue as a child class.

This allows to address queues individually and graft them similar to regular
classes. Additionally it presents an accumulated view of the statistics of
all real root qdiscs in the dummy root.

Two new callbacks are added to the qdisc_ops and qdisc_class_ops:

- cl_ops->select_queue selects the tx queue number for new child classes.

- qdisc_ops->attach() overrides root qdisc device grafting to attach
  non-shared qdiscs to the queues.
