Net-detect is an option of wowlan to allow the device to
be woken up from suspend mode when configured network is detected.
When user enables net-detect and lets the device enter suspend
state, wowlan firmware will periodically scan until beacon or
probe response of configured networks are received.
Between two scans, wowlan firmware keeps wifi chip in idle mode
to reduce power consumption. If configured networks are detected,
wowlan firmware will trigger resume process.

Pattern match is an option of wowlan to allow the device
to be woken up from suspend mode when receiving packets
matched user-designed patterns.
The patterns are written into hardware cam in suspend flow
if users have set up them. If packets matched designed

Wake on WLAN(wowlan) is a feature which allows devices
to be woken up from suspend state through wlan events.
When user enables wowlan feature and then let the device
enter suspend state, wowlan firmware will be loaded by
the driver and periodically monitors wifi packets.
Power consumption of wifi chip will be reduced in this
state.
If wowlan firmware detects that specific wlan event
happens, it will issue wakeup signal to trigger resume
process. Driver will load normal firmware and let wifi
chip return to the original state.
Currently supported wlan events include receiving magic packet,
rekey packet and deauth packet, and disconnecting from AP.

When data is received on the READ channel, the matching logic for cmds
that are waiting for a reply is currently hard-coded into the channel's
main IO callback.
Move this into a per-cmd callback, so that we can apply custom matching
logic for each individual cmd.
This also allows us to remove the coarse-grained check for unexpected
non-IPA replies, since they will no longer match against _all_ pending
cmds.
Note that IDX cmds use _no_ matcher, since their reply is synchronously

Before commit 1e58252e33 ("mwifiex: Fix heap overflow in
mmwifiex_process_tdls_action_frame()"),
mwifiex_process_tdls_action_frame() already had too many magic numbers.
But this commit just added a ton more, in the name of checking for
buffer overflows. That seems like a really bad idea.
Let's make these magic numbers a little less magic, by
(a) factoring out 'pos[1]' as 'ie_len'
(b) using 'sizeof' on the appropriate source or destination fields where
possible, instead of bare numbers
(c) dropping redundant checks, per below.
Regarding redundant checks: the beginning of the loop has this:
if (pos + 2 + pos[1] > end)
break;
but then individual 'case's include stuff like this:
if (pos > end - 3)
return;
if (pos[1] != 1)
return;
Note that the second 'return' (validating the length, pos[1]) combined
with the above condition (ensuring 'pos + 2 + length' doesn't exceed
'end'), makes the first 'return' (whose 'if' can be reworded as 'pos >
end - pos[1] - 2') redundant. Rather than unwind the magic numbers
there, just drop those conditions.

when DUT was configured as AP and associated with 50+ STAs.
For QCA9984/QCA9888, the DMA_BURST_SIZE register controls the AXI burst size
of the RD/WR access to the HOST MEM.
0 - No split , RAW read/write transfer size from MAC is put out on bus
as burst length
1 - Split at 256 byte boundary
2,3 - Reserved
With PCIe protocol analyzer, we can see DMA Read crossing 4KB boundary when
issue happened. It broke PCIe spec and caused PCIe stuck. So revert
the default value from 0 to 1.

return error status and stop transfer the left data. For example,
the really RX len is 286 bytes, then it will split to 2 blocks in
sdio_io_rw_ext_helper, one is 256 bytes, left is 30 bytes, if the
first 256 bytes get an error status by mmc_should_fail_request,then
the left 30 bytes will not read in this RX operation. Then when the
next RX arrive, the left 30 bytes will be considered as the header
of the read, the top 8 bytes will be considered as ath10k_htc_hdr,
but actually the 8 bytes is not the ath10k_htc_hdr, so the act_len
from this ath10k_htc_hdr is not correct, if it is a big value, such
as 57013, it will trigger skb_panic.
Drop the skb with invalid length will be reasonable.
This patch only effect sdio chips.
Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00029.

The WiFi firmware found on sm8150 requires that the QDSS clock is
ticking in order to operate, so add an optional clock to the binding to
allow this to be specified in the sm8150 dts and add the clock to the
list of clocks in the driver.

The description of ath10k_pci_dump_memory_sram() is inaccurate, an error
can never be returned, it is always the length. Update the comment to
reflect.

ath10k_pci_dump_memory_reg() will try to access memory of type
ATH10K_MEM_REGION_TYPE_IOREG however, if a hardware restart is in progress
this can crash a system.
Individual ioread32() time has been observed to jump from 15-20 ticks to >
80k ticks followed by a secure-watchdog bite and a system reset.
Work around this corner case by only issuing the read transaction when the
driver state is ATH10K_STATE_ON.

Syzbot managed to trigger a use after free "KASAN: use-after-free Write
in hci_sock_bind". I have reviewed the code manually and one possibly
cause I have found is that we are not holding lock_sock(sk) when we do
the hci_dev_put(hdev) in hci_sock_release(). My theory is that the bind
and the release are racing against each other which results in this use
after free.
