Whenever htt rx indication i.e target to host messages are received
on rx copy engine (CE5), the message will be freed after processing
the response. Then CE 5 will be refilled with new descriptors at
post rx processing. This memory alloc and free operations can be avoided
by reusing the same descriptors.
During CE pipe allocation, full ring is not initialized i.e n-1 entries
are filled up. So for CE 5 full ring should be filled up to reuse
descriptors. Moreover CE 5 write index will be updated in single shot
instead of incremental access. This could avoid multiple pci_write and
ce_ring access. From experiments, It improves CPU usage by ~3% in IPQ4019

"DQA" is shorthand for "dynamic queue allocation". This
enables on-demand allocation of queues per RA/TID rather than
statically allocating per vif, thus allowing a potential
benefit of various factors.
Please refer to the DOC section this patch adds to sta.h to
see a more in-depth explanation of this feature.
There are many things to take into consideration when working
in DQA mode, and this patch is only one in a series. Note that
default operation mode is non-DQA mode, unless the FW
indicates that it supports DQA mode.
This patch enables support of DQA for a station connected to
an AP, and works in a non-aggregated mode.
When a frame for an unused RA/TID arrives at the driver, it
isn't TXed immediately, but deferred first until a suitable
queue is first allocated for it, and then TXed by a worker
that both allocates the queues and TXes deferred traffic.
When a STA is removed, its queues goes back into the queue
pools for reuse as needed.

We insert padding if the MAC header's size is not a multiple of 4
to ensure that the SNAP header is DWORD aligned. When we do so, we
let the firmware know by setting a bit in Tx command
(TX_CMD_FLG_MH_PAD) which will instruct the firmware to drop those
2 bytes before sending the frame.
However, this is not needed for AMSDU as the sub frame header (14B)
complements the MAC header (26B) so that the SNAP header is DWORD
aligned without adding any pad.
Until 9000, the firmware didn't check the TX_CMD_FLG_MH_PAD bit
but rather checked the length of the MAC header itself and
assumed the entity that enqueued the frame (driver or internal
firmware code) added the pad.
Since the driver inserted the pad even for AMSDU this logic applied.
Note that the padding is a DMA optimization but it's not strictly
needed, so we could pad even if it was not needed.
However, the CSUM hardware introduced for the 9000 devices requires
to not pad AMSDU as it is not needed, and will fail if such a pad
exists.
Due to older FW not checking the padding bit but checking the mac
header size itself - we cannot do this adjustments for older
generations.
Do not align the size if it is an AMSDU and HW checksum is enabled -
which will only happen on 9000 devices and on.

qca4019 calibration data is stored in the host memory and it's mandatory
to download it even before reading board id and chip id from the target.
Also, there is a need to execute otp (download and run) twice, one after
cal data download and another one after board data download.
Existing cal data file name 'cal-<bus>-<id>.bin' and device tree entry
'qcom,ath10k-calibration-data' used in ath10k has assumption that it
carries other data (like board data) also along with the calibration data.
But, qca4019 cal data contains pure calibration data (doesn't include
any other info). So, using existing same cal file name and DT entry
in qca4019 case would alter the purpose of it. To avoid this, new cal
file name 'pre-cal-<bus>-<id>.bin' and new device tree entry name
'qcom,ath10k-pre-calibration-data are introduced.
Overall qca4019's firmware download sequence would look like,
1) Download cal data (either from a file or device tree entry)
at the address specified by target in the host interest area
member "hi_board_data".
2) Download otp and run with 0x10 (PARAM_GET_EEPROM_BOARD_ID)
as a argument.
At this point, otp will take back up of downloaded cal data
content in another location in the target and return valid
board id and chip id to the host.
3) Download board data at the address specified by target
in host interest area member "hi_board_data".
4) Download otp and run with 0x10000 (PARAM_FLASH_SECTION_ALL) as
a argument.
Now otp will apply cal data content from it's backup on top
of board data download in step 3 and prepare final data base.
5) Download code swap and athwlan binary content.
Above sequences are implemented (step 1 to step 4) in the name of

Paging contains 3 sections in the fw. The first for the paging separator,
The second for the CSS block, the third with the paging data.
Currently if the driver finds the paging separator, and there is only
section left (CSS), once reading the CSS section, the driver will
attempt to read the paging data and will go out of the arrays bounds.
Make sure that the FW image contains the right amount of sections for
paging.

Currently the driver has 2 buffers for paging:
1. paging db - this contains all of the pages that were in the FW
image, that the driver stores for the FW. This is allocated for each
block separately (not contiguous).
2. download buffer - we need to provide this empty buffer for the
iwl_sdio_load_fw_chunk function to copy the requested pages to the shared
memory. This is one big buffer of contiguous memory whose size is the
size of all the blocks that the fw paging section can contain.
This download buffer size is too big, and causes the allocation to fail
sometimes. Since the driver allocates memory for each block separately,
it is not possible for the FW to request all of the pages in one request
(the FW gives an address and size, so blocks need to be contiguous for
this to happen), therefore the FW is limited to request only one block.
Decrease the size of the paging download buffer to be the size of a
paging block.

Pull networking updates from David Miller:
"Highlights:
1) Support more Realtek wireless chips, from Jes Sorenson.
2) New BPF types for per-cpu hash and arrap maps, from Alexei
Starovoitov.
3) Make several TCP sysctls per-namespace, from Nikolay Borisov.
4) Allow the use of SO_REUSEPORT in order to do per-thread processing
of incoming TCP/UDP connections. The muxing can be done using a
BPF program which hashes the incoming packet. From Craig Gallek.
5) Add a multiplexer for TCP streams, to provide a messaged based
interface. BPF programs can be used to determine the message
boundaries. From Tom Herbert.
6) Add 802.1AE MACSEC support, from Sabrina Dubroca.
7) Avoid factorial complexity when taking down an inetdev interface
with lots of configured addresses. We were doing things like
traversing the entire address less for each address removed, and
flushing the entire netfilter conntrack table for every address as
well.
8) Add and use SKB bulk free infrastructure, from Jesper Brouer.
9) Allow offloading u32 classifiers to hardware, and implement for
ixgbe, from John Fastabend.
10) Allow configuring IRQ coalescing parameters on a per-queue basis,
from Kan Liang.
11) Extend ethtool so that larger link mode masks can be supported.
From David Decotigny.
12) Introduce devlink, which can be used to configure port link types
(ethernet vs Infiniband, etc.), port splitting, and switch device
level attributes as a whole. From Jiri Pirko.
13) Hardware offload support for flower classifiers, from Amir Vadai.
14) Add "Local Checksum Offload". Basically, for a tunneled packet
the checksum of the outer header is 'constant' (because with the
checksum field filled into the inner protocol header, the payload
of the outer frame checksums to 'zero'), and we can take advantage
of that in various ways. From Edward Cree"

Frames that are transmitted via MGMT_TX are using reserved descriptor
slots in firmware. This limitation is for the htt_mgmt_tx path itself,
not for mgmt frames per se. In 16 MBSSID scenario, these reserved slots
will be easy exhausted due to frequent probe responses. So for 10.4
based solutions, probe responses are limited by a threshold (24).
management tx path is separate for all except tlv based solutions. Since
tlv solutions (qca6174 & qca9377) do not support 16 AP interfaces, it is
safe to move management descriptor limitation check under mgmt_tx
function. Though CPU improvement is negligible, unlikely conditions or
never hit conditions in hot path can be avoided on data transmission.

Whenever firmware is configuring operating channel during scan or
home channel, channel change event will be indicated to host. In some
cases (device probe/ last vdev down), target will be configured to
default channel whereas host is unaware of target's operating channel.
This leads to packet drop due to unknown channel and kernel log will be
filled up with "no channel configured; ignoring frame(s)!". Fix that

Code that was added back in 2.6.38 has an obvious overflow
when accessing a static array, and at the time it was added
only a code comment was put in front of it as a reminder
to have it reviewed properly.
This has not happened, but gcc-6 now points to the specific
overflow:
drivers/net/wireless/ath/ath9k/eeprom.c: In function 'ath9k_hw_get_gain_boundaries_pdadcs':
drivers/net/wireless/ath/ath9k/eeprom.c:483:44: error: array subscript is above array bounds [-Werror=array-bounds]
maxPwrT4[i] = data_9287[idxL].pwrPdg[i][4];
~~~~~~~~~~~~~~~~~~~~~~~~~^~~
It turns out that the correct array length exists in the local
'intercepts' variable of this function, so we can just use that
instead of hardcoding '4', so this patch changes all three
instances to use that variable. The other two instances were
already correct, but it's more consistent this way.

Certain 6004 firmware releases redefine the WMI_TXE_NOTIFY_EVENTID event
number and sends the new event frequently. However it doesn't have the
tx-err-notify feature and thus this firmware capability flag isn't set on
the firmware package. By guarding the processing of this event by the same
method we guard the sending of the WMI_SET_TXE_NOTIFY_CMDID command, we
can ignore the spurious event that we don't know how to process.
Without this change we call cfg80211_cqm_txe_notify() with possibly bad

Newer generation chips use a 40 byte TX descriptor, compared to the
32 byte descriptor used on older chips.
This adds the definition for the 40 byte descriptor.

Older chips use RF register 0x24 to set the thermal meter. Newer chips
use register 0x42.
This change makes sure to set the correct thermal meter register
depending on the chip.

Newer generation chips have more channels groups. In order to carry
the larger arrays in common structures, bump the array sizes to
match.

Some newer chips have more channel groups in their efuse parameter
tables, so use the size of the source, rather than the destination
when copying them out. This avoids copying garbage when increasing the
common array sizes.
