2289bef25e ath10k: enable firmware peer stats info for wmi tlv
For wmi tlv type, firmware disable peer stats info by default, after
enable it, firmware will report WMI_TLV_PEER_STATS_INFO_EVENTID if
ath10k send WMI_TLV_REQUEST_PEER_STATS_INFO_CMDID to firmware.

Enable it will only set a flag in firmware, firmware will not report
it without receive request WMI command.

Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00042.

59a022cc14 ath10k: add statistics of tx retries and tx failed when tx complete disable
When tx complete is disabled, all tx status will be set with status
HTT_TX_COMPL_STATE_ACK and indicate to mac80211 by ieee80211_tx_status,
then it does not have the statistics for retries and failed packets.
count of tx retries and tx failed of command "iw wlan0 station dump"
are both 0. If tx complete is not disabled, then firmware report the
tx status and ath10k indicate the status to mac80211, then mac80211
save the statistics and command "iw wlan0 station dump" show them.

for example:
localhost ~ # iw dev wlan0 station dump
Station 3c:28:6d:96:fd:69 (on wlan0)
	inactive time:	5 ms
	rx bytes:	1325012
	rx packets:	6477
	tx bytes:	85264
	tx packets:	518
	tx retries:	0
	tx failed:	0

This patch only effect chips with tx complete disabled, e.g. SDIO.

with this patch, output of command "iw dev wlan0 station dump":
Station c4:04:15:5d:97:22 (on wlan0)
        inactive time:  608 ms
        rx bytes:       180366
        rx packets:     991
        tx bytes:       98765577
        tx packets:     64624
        tx retries:     14682
        tx failed:      47086

4913e67563 ath10k: enable rx duration report default for wmi tlv
When run command "iw dev wlan0 station dump", the rx duration is 0.
When firmware indicate WMI_UPDATE_STATS_EVENTID, extended flag of
statsis not set by default, so firmware do not report rx duration.

one sample:
localhost # iw wlan0 station dump
Station c4:04:15:5d:97:22 (on wlan0)
        inactive time:  48 ms
        rx bytes:       21670
        rx packets:     147
        tx bytes:       11529
        tx packets:     100
        tx retries:     88
        tx failed:      36
        beacon loss:    1
        beacon rx:      31
        rx drop misc:   47
        signal:         -72 [-74, -75] dBm
        signal avg:     -71 [-74, -75] dBm
        beacon signal avg:      -71 dBm
        tx bitrate:     54.0 MBit/s MCS 3 40MHz
        rx bitrate:     1.0 MBit/s
	rx duration:    0 us

This patch enable firmware's extened flag of stats by setting flag
WMI_TLV_STAT_PEER_EXTD of ar->fw_stats_req_mask which is set in
ath10k_core_init_firmware_features via WMI_REQUEST_STATS_CMDID.

After apply this patch, rx duration show value with the command:
Station c4:04:15:5d:97:22 (on wlan0)
        inactive time:  883 ms
        rx bytes:       44289
        rx packets:     265
        tx bytes:       10838
        tx packets:     93
        tx retries:     899
        tx failed:      103
        beacon loss:    0
        beacon rx:      78
        rx drop misc:   46
        signal:         -71 [-74, -76] dBm
        signal avg:     -70 [-74, -76] dBm
        beacon signal avg:      -70 dBm
        tx bitrate:     54.0 MBit/s MCS 3 40MHz
        rx bitrate:     1.0 MBit/s
        rx duration:    358004 us

This patch do not have side effect for all chips, because function
ath10k_debug_fw_stats_request is already exported to debugfs
"fw_stats" and WMI_REQUEST_STATS_CMDID is safely sent after condition
checked by ath10k_peer_stats_enabled in ath10k_sta_statistics.

aac392d855 ath10k: Fix the invalid tx/rx chainmask configuration
The driver is allowing the invalid tx/rx chainmask configuration
(other than 1,3,7,15) set by the user. It causes the firmware
crash due to the invalid chainmask values.

Hence, reject the invalid chainmask values in the driver by not
sending the pdev set command to the firmware.

dd7fc5545b ath10k: add flush tx packets for SDIO chip
When station connected to AP, and run TX traffic such as TCP/UDP, and
system enter suspend state, then mac80211 call ath10k_flush with set
drop flag, recently it only send wmi peer flush to firmware and
firmware will flush all pending TX packets, for PCIe, firmware will
indicate the TX packets status to ath10k, and then ath10k indicate to
mac80211 TX complete with the status, then all the packets has been
flushed at this moment. For SDIO chip, it is different, its TX
complete indication is disabled by default, and it has a tx queue in
ath10k, and its tx credit control is enabled, total tx credit is 96,
when its credit is not sufficient, then the packets will buffered in
the tx queue of ath10k, max packets is TARGET_TLV_NUM_MSDU_DESC_HL
which is 1024, for SDIO, when mac80211 call ath10k_flush with set drop
flag, maybe it have pending packets in tx queue of ath10k, and if it
does not have sufficient tx credit, the packets will stay in queue
untill tx credit report from firmware, if it is a noisy environment,
tx speed is low and the tx credit report from firmware will delay more
time, then the num_pending_tx will remain > 0 untill all packets send
to firmware. After the 1st ath10k_flush, mac80211 will call the 2nd
ath10k_flush without set drop flag immediately, then it will call to
ath10k_mac_wait_tx_complete, and it wait untill num_pending_tx become
to 0, in noisy environment, it is esay to wait about near 5 seconds,
then it cause the suspend take long time.

1st and 2nd callstack of ath10k_flush

db6d9e9e8b mac80211: Fix setting txpower to zero
With multiple VIFS ath10k, and probably others, tries to find the
minimum txpower for all vifs and uses that when setting txpower in
the firmware.

If a second vif is added and starts to scan, it's txpower is not
initialized yet and it set to zero.

ath10k had a patch to ignore zero values, but then it is impossible
to actually set txpower to zero.

So, instead initialize the txpower to INT_MIN in mac80211, and let
drivers know that means the power has not been set and so should
be ignored.

This should fix regression in:

911bde0fe5 mac80211: Turn AQL into an NL80211_EXT_FEATURE
Instead of just having an airtime flag in debugfs, turn AQL into a proper
NL80211_EXT_FEATURE, so drivers can turn it on when they are ready, and so
we also expose the presence of the feature to userspace.

This also has the effect of flipping the default, so drivers have to opt in
to using AQL instead of getting it by default with TXQs. To keep
functionality the same as pre-patch, we set this feature for ath10k (which
is where it is needed the most).

While we're at it, split out the debugfs interface so AQL gets its own
per-station debugfs file instead of using the 'airtime' file.

[Johannes:]
This effectively disables AQL for iwlwifi, where it fixes a number of
issues:
 * TSO in iwlwifi is causing underflows and associated warnings in AQL
 * HE (802.11ax) rates aren't reported properly so at HE rates, AQL could
   never have a valid estimate (it'd use 6 Mbps instead of up to 2400!)

382e51c139 ath10k: set WMI_PEER_AUTHORIZE after a firmware crash
After the firmware crashes ath10k recovers via ieee80211_reconfig(),
which eventually leads to firmware configuration and including the
encryption keys. However, because there is no new auth/assoc and
4-way-handshake, and firmware set the authorize flag after
4-way-handshake, so the authorize flag in firmware is not set in
firmware without 4-way-handshake. This will lead to a failure of data
transmission after recovery done when using encrypted connections like
WPA-PSK. Set authorize flag after installing keys to firmware will fix
the issue.

This was noticed by testing firmware crashing using simulate_fw_crash
debugfs file.

1382993f88 ath10k: add support for hardware rfkill
When hardware rfkill is enabled in the firmware it will report the
capability via using WMI_TLV_SYS_CAP_INFO_RFKILL bit in the WMI_SERVICE_READY
event to the host. ath10k will check the capability, and if it is enabled then
ath10k will set the GPIO information to firmware using WMI_PDEV_SET_PARAM. When
the firmware detects hardware rfkill is enabled by the user, it will report it
via WMI_RFKILL_STATE_CHANGE_EVENTID. Once ath10k receives the event it will
send wmi command WMI_PDEV_SET_PARAM to the firmware to enable/disable the radio
and also notifies cfg80211.

We can't power off the device when rfkill is enabled, as otherwise the
firmware would not be able to detect GPIO changes and report them to the
host. So when rfkill is enabled, we need to keep the firmware running.

This bug appears to have been added between 4.0 (which works for us),
and 4.4, which does not work.

I think this is because the tx-offchannel logic gets in a loop when
ath10k_mac_tx_frm_has_freq(ar) is false, so pkt is never actually
sent to the firmware for transmit.

This patch fixes the problem on 4.9 for me, and now HS20 clients
can work again with my firmware.

306547608c ath10k: switch to ieee80211_tx_dequeue_ni
Since ath10k_mac_tx_push_txq() can be called from process context, we
must explicitly disable softirqs before the call into mac80211.

By calling ieee80211_tx_dequeue_ni() instead of ieee80211_tx_dequeue()
we make sure softirqs are always disabled even in the case when
ath10k_mac_tx_push_txq() is called from process context.

Calling ieee80211_tx_dequeue_ni() with softirq's already disabled
(e.g., from softirq context) should be safe as the local_bh_disable()
and local_bh_enable() functions (called from ieee80211_tx_dequeue_ni)
are fully reentrant.

ath10k_bss_info_changed() handles various events from the upper layers. It
parses the changed bitfield and then configures the driver/firmware

independent of each other - but in the same function.

The commit f279294e9e ("ath10k: add support for configuring management

prematurely when some precondition was not fulfilled. All new event
handlers added after the BSS_CHANGED_BASIC_RATES event handler would then

b3281c6cb7 ath10k: free beacon buf later in vdev teardown
My wave-1 firmware often crashes when I am bringing down
AP vdevs, and sometimes at least some machines lockup hard
after spewing IOMMU errors.

I don't see the same issue in STA mode, so I suspect beacons
are the issue.

Moving the beacon buf deletion to later in the vdev teardown
logic appears to help this problem.  Firmware still crashes
often, but several iterations did not show IOMMU errors and
machine didn't hang.

33410a5146 ath10k: add support for controlling tx power to a station
This patch will add the support to control the transmit power for traffic
to a station associated with the AP.

Underlying firmware will enforce that the maximum tx power will be based
on the regulatory requirements. If the user given transmit power is greater
than the allowed tx power in the given channel, then the firmware will use
the maximum tx power in the same channel.

Max and Min tx power values will depends on no of tx chain masks,
for QCA9984 allowed tx power range values from 6 to 23.

When 0 is sent to the firmware as tx power, it will revert to the default
tx power for the station.

8b97b055dc ath10k: fix failure to set multiple fixed rate
Currently, below fixed rate commands are broken,
iw wlanx set bitrates legacy-<2.4|5> ht-mcs-<2.4|5> vht-mcs-<2.4|5> \
<NSS:MCSx>
iw wlanx set bitrates legacy-<2.4|5> <legacy rate> ht-mcs-<2.4|5> \
vht-mcs-<2.4|5> <NSS:MCSx>

There are two methods to set fixed rate, both failed,
- Use vdev fixed rate command
  This command only support one single rate, but it's broken due to
  mac80211 change commit e8e4f5280d ("mac80211: reject/clear user
  rate mask if not usable"), which requires user to specify at least
  one legacy rate. So we can't use this command to set ht/vht single
  rate any more.
- Use peer_assoc command
  This command can update rx capability for multiple rates, it will
  work fine for ht mcs rates, as each supported mcs can be advertised
  in ht_mcs index mask. But this will not work with vht rates because,
  as per the vht mcs capability advertisement, there are only two bits
  to indicate the supported mcs. E.g. only support 0-7, 0-8, 0-9.

So introduced new WMI command: WMI_PEER_PARAM_FIXED_RATE. After peer
assoc, the peer fixed rate cmd will work for that specific peer.
Remaining peers will use auto rate. If both vdev fixed rate and peer
fixed rates are given, peer fixed rate will take effect to peers for
which this cmd is given. Remaining peers in that vdev, will use vdev
fixed rate.

2b4a669802 mac80211: make ieee80211_schedule_txq schedule empty TXQs
Currently there is no way for the driver to signal to mac80211 that it should
schedule a TXQ even if there are no packets on the mac80211 part of that queue.
This is problematic if the driver has an internal retry queue to deal with
software A-MPDU retry.

This patch changes the behavior of ieee80211_schedule_txq to always schedule
the queue, as its only user (ath9k) seems to expect such behavior already:
it calls this function on tx status and on powersave wakeup whenever its
internal retry queue is not empty.

Also add an extra argument to ieee80211_return_txq to get the same behavior.

This fixes an issue on ath9k where tx queues with packets to retry (and no
new packets in mac80211) would not get serviced.

4920ce3bf7 ath10k: add dynamic vlan support
Multicast/broadcast traffic destined for a particular vlan group will
always be encrypted in software. To enable dynamic VLANs, it requires
driver support for sending software encrypted packets.

In ath10k, sending software encrypted frames is allowed only when we insmod
the driver with cryptmode param set to 1, this configuration disables
hardware crypto and enables RAW mode implicitly. Since, enabling raw
mode has performance impact, this cannot be considered as an ideal
solution for supporting VLANs in the driver.

As an alternative take, in this approach, cryptographic keys for
unicast traffic (per peer PTKs) and keys for non-vlan group traffic
will be configured in hardware, allowing hardware encryption for unicast
and non-vlan group traffic. Only vlan group traffic will be encrypted in
software and pushed to the target with encap mode set to RAW in the TX
descriptors.

Not all firmwares can support this type of key configuration(having few
keys installed in hardware and few only in software); for this purpose a
new WMI service flag "WMI_SERVICE_PER_PACKET_SW_ENCRYPT" is introduced to
advertise this support.

Also, adding the logic required to send sw encrypted frames in raw mode.
