With USB, it's a case of the same bug fix first going into net-next

039a0051ec ath10k: allocate fw resources for iface combinations
The number of 3 vdevs wasn't enough to handle the
worst case for interface combinations in practice.

wpa_supplicant may need up to 4 vifs to have 2
vifs actually connected, i.e. p2pdev + client + 2x
p2p (either p2p client or p2p go).

This fixes worst case warning:

  Free vdev map is empty, no more interfaces allowed.

This keeps the ability to associate 32 stations in
AP mode at the cost of not being able to guarantee
that under all circumstances, i.e. some
combinations may consume additional fw peer
entries for internal purposes leaving less
resource for stations in AP mode.

6bab2e19c5 cfg80211: pass name_assign_type to rdev_add_virtual_intf()
This will expose in /sys whether the ifname of a device is set by
userspace or generated by the kernel. The latter kind (wlanX, etc)
is not deterministic, so userspace needs to rename these devices
to names that are guaranteed to stay the same between reboots. The
former, however should never be renamed, so userspace needs to be
able to reliably tell the difference.

Similar functionality was introduced for the rtnetlink core in
commit 5517750f05 ("net: rtnetlink - make create_link take name_assign_type")

8348db2984 ath10k: add ATH10K_FW_IE_HTT_OP_VERSION
Target to host HTT messages are conflicting between 10.x and other
firmware revisions. By maintaining separate HTT T2H tables for each
firmware revisions (main, 10x and tlv) similar to WMI abstraction,
solves the conflicts. Add ATH10K_FW_IE_HTT_OP_VERSION so that the firmware can
advertise the HTT interface to ath10k.

This fix is needed to get management frames over HTT (ie.
ATH10K_FW_FEATURE_HAS_WMI_MGMT_TX disabled) working with 10.2.4.48-2 firmware.
Otherwise there will be unknown htt events and nothing works:

[30087.438343] ath10k_pci 0000:02:00.0: htt event (19) not handled
[30087.448691] ath10k_pci 0000:02:00.0: htt event (19) not handled
[30149.032974] ath10k_pci 0000:02:00.0: htt event (19) not handled

If the firmware does not have ATH10K_FW_IE_HTT_OP_VERSION use the main HTT
interface. That way old firmware images will still work.

9936fa5908 ath10k: move driver state check before setting throttle
Since thermal daemon is unaware of the device state, it might
try to adjust the throttle state when the device is powered down.
So the driver caches the value and will configure it while
powering up the target. The cached value will be programed later
once the device is brought up. In such case, returning error
status is confusing and misleading the user application. Hence
moving the driver state check before sending wmi command to target.

To solve this, order hardware offload block to not remove
SNAP header. This adds extra 6 bytes between addresses and
ethertype, making it 20 bytes total. This way, both buffer and
IP header are 4*n aligned. Remaining is only to remove SNAP
by shifting addresses 6 bytes. This involves data copying, so
this feature should be disabled unless required by the platform.

Module parameter "rx_align_2" (bool, default - false)
introduced to control this feature. Feature is completely disabled
when parameter is false.

5dc0f1db41 ath10k: protect driver from unsolicited htc ep0 events
Some firmware revisions (tested with qca6174
rm2.0-00088) deliver unsolicited unknown (kind of
garbled) HTC ep0 event to host in some cases.

This issue was mainly observed with both qca988x
and qca6174 being installed on a single host
system. During driver probing if qca6174 booting
sequences were somehow deferred (e.g. by qca988x
implicitly making some resources busy presumably)
the unsolicited event would came around 1s after
ATH10K_HTC_MSG_READY_ID was delivered to host for
qca6174.

The unsolicited event would confuse driver and
cause HTT initialization (and subsequently
driver probing) to fail.

Make the ep0 event processing more robust. The
event will still be caught but instead will
only generate a warning now.

8bad8dcd0c ath10k: strip qos data bit always
NativeWifi tx mode expects QoS Data frames to be
delivered as Data frames with QoS part (e.g. tid)
being delievered out-of-band in fw tx command.

The QoS bit wasn't stripped before submitting to
firmware.

Stripping fixes two known problems:

 * qca6174 IOT with some APs, e.g.
   Cisco AIR-AP 1252 (which would crash after
   ath10k association). Some ath9k APs would
   crash as well.

 * sniffing own tx frames via radiotap because,
   e.g. wireshark was seeing QoS bit set but
   since QoS Control was stripped in ath10k it
   would parse beginning of LLC/SNAP

>From debugability point of view this removes the
ability to distinguish QoS from non-QoS frames
when sniffing own tx via radiotap. On the other
hand frames can be now parsed correctly without
special software modification.

ab5e290a86 ath5k: fix reset race
To prepare for reset ath5k should finish all asynchronous tasks. At
first, it disables the interrupt generation, then it waits for the
interrupt handler and tasklets completion, and then proceeds to the HW
configuration update. But it does not consider that the interrupt
handler or tasklet re-enables the interrupt generation. And we fall in a
situation when ath5k assumes that interrupts are disabled, but it is
not.

This can lead to different consequences, such as reception of the frame,
when we do not expect it. Under certain circumstances, this can lead to
the following warning:

  WARNING: at ath5k/base.c:589 ath5k_tasklet_rx+0x318/0x6ec [ath5k]()

Fix this issue by adding a new status flag, which forbids to re-enable
the interrupt generation until the HW configuration is completed.

Note: previous patch, which reorders the Rx disable code helps to avoid
the above warning, but not fixes the root cause of unexpected frame
receiving.

4a2f248f9e ath5k: channel change fix
ath5k updates the channel pointer and after that it stops the Rx logic
and apply channel to HW. In case of channel switch, such sequence
creates a small window when a frame, which is received on the old
channel is considered as a frame received on the new one.

The most notable consequence of this situation occurs during the switch
from 2 GHz band (CCK+OFDM) to the 5GHz band (OFDM-only). Frame received
with CCK rate, e.g. beacon received at the 1mbps, causes the following
warning:

The easiest way to reproduce this warning is to run scan with dualband
NIC in noisy environments, when the channel 11 runs multiple APs. In my
tests if the APs num >= 12, the warning appears in the first few
seconds of scanning.

In order to fix this, the Rx disable code moved to a higher level and
placed before the channel pointer update. This is also makes the code a
bit more symmetrical, since we disable and enable the Rx in the same
function.

In fact, at the pointer update time new frames should not appear,
because interrupt generation at this point should already be disabled.
The next patch should address this issue.

7cc4573e85 ath10k: fix WPA crypto
Commit 370e567363 ("ath10k: fix broken traffic for 802.1x in client mode")
introduced a regression on WPA crypto. All keys were treated as if they were
WEP which resulted in WPA being incorrectly installed to fw/hw and subsequently
no traffic.

bff414c3d2 ath10k: fix CAC regression
Commit 548462133d ("ath10k: fix interrupt storm") introduced a
regression. The condition responsible for bringing up monitor vdev was broken
and it was never started for CAC so effectivelly CAC would not detect radar
pulses.

Mistakenly v1 of `ath10k: fix AP/IBSS CSA with
template based fw`
(81a9a17db5) was
applied.

This patch applies the missing bits from v2:
 * remove unnecessary locking
 * add some (sanity) checks

There are no practical functionality differences
between v1 and v2.

9ff4be96eb ath10k: save/restore pci config space properly
The check was't really necessary and couldn't even
work to begin with because pci_restore_state()
restores only first 64 bytes of PCI configuration
space.

Actually the PCI subsystem takes care of this so
there's no need for explicit calls to save PCI
state in ath10k.

This is necessary for future WoWLAN support.

548462133d ath10k: fix interrupt storm
Promiscuous mode is enabled when wlan interface is added to
bridge. ath10k creates a monitor mode when promiscuous mode
is enabled. When monitor vdev is running along with other
vdev(s) there is a huge number of interrupts generated
especially in noisy condition. Fix this by not enabling
promiscuous(monitor) mode when already a vdev is running.
As disabling promiscuous mode may have issues with 4-address
bridging in STA mode, the change is done specific to non-sta/ibss
mode types. This does not change the support of virtual interface of
type monitor along with other vdevs of any type.

This could fix management frame drop in fw due to unavailable
buffers because in monitor mode device receives everything seen
on the air. In noisy condition, disabling monitor mode helps assoc
go through without any issue.
