Mohamed Abbas 951891c7ef iwlwifi: clear scanning bits upon failure
In iwl_bg_request_scan function, if we could not send a
scan command it will go to done.
In done it does the right thing to call mac80211 with
scan complete, but the problem is STATUS_SCAN_HW is still
set causing any future scan to fail. Fix by clearing the scanning status
bits if scan fails.

Sujith 8b30b1fe36 mac80211: Re-enable aggregation
Wireless HW without any dedicated queues for aggregation
do not need the ampdu_queues mechanism present right now

This is only an interim hack until Intel fixes the requeue issue.

Tomas Winkler 499b188303 iwlwifi: fix TX cmd dma unmapping
This patch:
1. fixes command DMA unmapping, this might be visible only
	on platforms where DMA unmapping is no noop such as PPC64 (not tested)
2. attaches correctly high memory part of the host command buffer
3. changes structure of TFD TB
	instead of describing transmit buffer (TB) tuple it describes single
	TB and makes code more readable on price of one unaligned access
4. eliminates using of IWL_GET/SET_BITs for TFD handling
5. renames TFD structures to mach the HW spec
6. reduces iwl_tx_info size by reserving first TB to the host command

This patch should not have any visible effect on x86 32

Wang Chen faf3994a9f airo: Kill directly reference of netdev->priv
We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug",
and I want to kill netdev->priv later, I decided to convert all the direct
reference of netdev->priv first.

In this driver, I don't simply use netdev_priv() to replace netdev->priv.

The reason is:
Pointer netdev->priv was changed in this driver, but it shouldn't.
Because the memory was allocated when alloc_netdev() and netdev->priv
should always point to that memory.

So I use netdev->ml_priv to replace netdev->priv.
After replacing, both ai and ai->wifidev->ml_priv point to the same memory.

Herton Ronaldo Krzesinski f8288317b5 rtl8187: add short slot handling for 8187B
This change adds short slot handling for 8187B variant of rtl8187 chips.
Some things to note about changes done:
* Values used are chosen to met 802.11-2007 spec. This raised a question
  about SIFS value used with 8187L: 0x22 (34) doesn't match any spec
  value. For now just don't change 8187L, but is something to be
  looked at.
* On 8187B, the location of EIFS register is at the same place as BRSR+1
  of struct rtl818x_csr. Unfortunately there is no clean way to
  accomodate 8187B differences currently, just use address of BRSR+1 and
  comment about it. The same thing happens for Ack timeout register,
  that is on CARRIER_SENSE_COUNTER location of 8187L. The eifs and ack
  timeout values are in units of 4us. All these registers information
  was gathered from references being the vendor gpl driver and 8180
  datasheet, unfortunately there is no information about this on 8187B
  datasheet. Also the ack timeout value was inspired by the same
  calculation as done on rt2x00.

Johannes Berg 7eb27af766 p54/rtl8187: fix up the seqno patch
Sorry about that, for some reason I didn't notice that I'd
left some unused variables in there.

Johannes Berg ae5eb02641 mac80211: rewrite HT handling
The HT handling has the following deficiencies, which I've
(partially) fixed:
 * it always uses the AP info even if there is no AP,
   hence has no chance of working as an AP
 * it pretends to be HW config, but really is per-BSS
 * channel sanity checking is left to the drivers
 * it generally lets the driver control too much

HT enabling is still wrong with this patch if you have more than
one virtual STA mode interface, but that never happens currently.
Once WDS, IBSS or AP/VLAN gets HT capabilities, it will also be
wrong, see the comment in ieee80211_enable_ht().

Additionally, this fixes a number of bugs:
 * mac80211: ieee80211_set_disassoc doesn't notify the driver any
             more since the refactoring
 * iwl-agn-rs: always uses the HT capabilities from the wrong stuff
               mac80211 gives it rather than the actual peer STA
 * ath9k: a number of bugs resulting from the broken HT API

I'm not entirely happy with putting the HT capabilities into
struct ieee80211_sta as restricted to our own HT TX capabilities,
but I see no cleaner solution for now.

Johannes Berg 9124b07740 mac80211: make retry limits part of hw config
Instead of having a separate callback, use the HW config callback
with a new flag to change retry limits.

Johannes Berg 94778280fa mac80211: provide sequence numbers
I've come to think that not providing sequence numbers for
the normal STA mode case was a mistake, at least two drivers
now had to implement code they wouldn't otherwise need, and
I believe at76_usb and adm8211 might be broken.

This patch makes mac80211 assign a sequence number to all
those frames that need one except beacons. That means that
if a driver only implements modes that do not do beaconing
it need not worry about the sequence number.
