iwlwifi: parse block ack responses correctly
Compressed BlockAck frames store the ACKs/NACKs in a 64-bit bitmap that starts
at the sequence number of the first frame sent in the aggregated batch. Note
that this is a selective ACKnowledgement following selective retransmission;
e.g., if frames 1,4-5 in a batch are ACKed then the next transmission will
include frames 2-3,6-10 (7 frames). In this latter case, the Compressed
BlockAck will not have all meaningful information in the low order bits -- the
semantically meaningful bits of the BA will be 0x1f3 (where the low-order frame
is seq 2).
The driver code originally just looked at the lower (in this case, 7) bits of
the BlockAck. In this case, the lower 7 bits of 0x1f3 => only 5 packets,
maximum, could ever be ACKed. In reality it should be looking at all of the
bits, filtered by those corresponding to packets that were actually sent. This
flaw meant that the number of correctly ACked packets could be significantly
underreported and might result in asynchronous state between TX and RX sides as
well as driver and uCode.
Fix this and also add a shortcut that doesn't require the code to loop through
all 64 bits of the bitmap but rather stops when no higher packets are ACKed.
In my experiments this fix greatly reduces throughput swing, making throughput
stable and high. It is also likely related to some of the stalls observed in
aggregation mode and maybe some of the buffer underruns observed, e.g.,

iwlwifi: reduce memory allocation
Currently, the driver allocates up to 19 skb pointers
for each TFD, of which we have 256 per queue. This
means that for each TX queue, we allocate 19k/38k
(an order 4 or 5 allocation on 32/64 bit respectively)
just for each queue's "txb" array, which contains only
the SKB pointers.
However, due to the way we use these pointers only the
first one can ever be assigned. When the driver was
initially written, the idea was that it could be
passed multiple SKBs for each TFD and attach all
those to implement gather DMA. However, due to
constraints in the userspace API and lack of TCP/IP
level checksumming in the device, this is in fact not
possible. And even if it were, the SKBs would be
chained, and we wouldn't need to keep pointers to
each anyway.
Change this to only keep track of one SKB per TFD,
and thereby reduce memory consumption to just one
pointer per TFD, which is an order 0 allocation per
transmit queue.

stopping another queue with fewer frames, this patch limits the number
of queued frames to a quarter of the total available tx buffers, minus
some reserved frames to be used for other purposes (e.g. beacons).
Because tx buffers are reserved for frames when they're staged in
software queues as well, the actual queue depth cannot be used for
this, so this patch stores a reference to the tx queue in the ath_buf
struct and keeps track of the total number of pending frames.

wl1271: Fix scan parameter handling for 5GHz
The 5GHz bands were scanned without the proper IE's in place, preventing
proper 5GHz scanning. This patches fixes the problem by storing a pointer
to the scan request (with the IE's) for all iterations of scan.

wl1271: Use proper rates for PSM entry/exit null-funcs for 5GHz
A fixed 1 mbps rate was used for the PSM entry/exit null-func frames. Fix this
by using the basic rates instead.

wl1271: the core wl1271 module shouldn't depend on SPI_MASTER
The core wl1271 module can also be used with SDIO, so it should not depend on
SPI_MASTER.

wl1271: Flush TX buffers to air before going to idle
The mac80211 changes to idle almost immediately after transmitting some
frames, such as deauth etc. When going to idle, the wl1271 is disconnected,
which causes TX frames already on buffers, but not yet transmitted, to be
deleted.
To make sure deauth frames reach the air, allow the TX buffers to flush
before proceeding to idle.

wl1271: Idle handling into own function
As there is more and more stuff triggered by going in and out of idle,
create a separate function for handling that.

wl1271: Prevent dropping of TX frames in joins
The wl1271 uses a session counter in CMD_JOIN and TX frame descriptors. This
counter is used to determine which frames to drop when the CMD_JOIN is
executed.
The driver executes CMD_JOIN multiple times upon association and sometimes
disassociation, and we don't want any frames to get lost.
Fix this by incrementing the session counter only when leaving idle (not every
CMD_JOIN as before.) Also, remove the TX flush flag from the CMD_JOIN options.

ath9k: cleanup: remove unneeded null check
We dereference "wmi" on the line before and also when we initialize "ah".
This check has always been after a dereference since the first commit a
couple months ago. Looking through the code, it looks like "wmi" can't
actually be null here so I just removed the check.
