AR_PHY_65NM_CH0_THERM and AR_CH0_THERM were supposed to refer to the
same register, however they had different SREV checks.
Remove the duplicate and use the checks. Since there were other SREV
checks present in the only place that uses this, this will probaby not
affect runtime behavior.

There were two paths in the code for "external" eeprom sources. The code
in eeprom.c only handled the cases where the eeprom data was loaded via
request_firmware. ahb.c and pci.c on the other hand had some duplicate
code which was only used when the eeprom data was passed via
ath9k_platform_data.
With this change all eeprom data handling is now unified in eeprom.c.

When an NL80211_DISCONNECT is sent to cfg80211, the driver's cfg80211
disconnect function sets the sme_state to SME_DISCONNECTED before receiving
a WMI_DISCONNECT_EVENT from the firmware. This caused cfg80211 to not know
that the connection is disconnected because the driver fails to notify
cfg80211 upon receiving WMI_DISCONNECT_EVENT from the firmware believing
it is already disconnected.

When disabling tethering after having enabled it, the ath6kl driver does
not set the IFF_LOWER_UP flag to 0 (carrier off) on the wlan interface.
The upper layers (eg. connman) are not notified of the tethering mode
status change. So, tethering can not be activated anymore.
This patch adds a netif_carrier_off() call when stopping AP mode to fix
the problem.

One minute after a successful connection, the kernel checks if the
frequency and the channel width are well configured for the country we
are in. (regulatory domain)
ath6kl driver was setting the NL80211_CHAN_HT20 channel without checking
for the HT capabilities. (we should have NL80211_CHAN_NO_HT in our
case because the firmware did not support HT)
This patch adds a check on ht_cap.ht_supported in order to create the
channel corresponding to the firmware capabilities.

When enabling WLAN tethering, a new AP is visible and a STA could
connect to it. When the STA tries to authenticate to the newly created
AP, the WPA authentication mechanism is stuck in the 1/4 msg of 4-Way
Handshake.
In ath6kl_rx(), the ath6kl_find_sta() function is looking for the
h_source field of the Ethernet frame header received by the STA. The
datap pointer that points to the Ethernet frame header is incorrect,
and was pointing at the wrong offset in the buffer.
This commit adds a pad_before_data_start offset to set the datap pointer
to the Ethernet frame header. datap->h_source parameter is now really
pointing to the source ethernet address and the authentication process
can continue.

Ideally wake_tx_queue should be used regardless as
it is a requirement for reducing bufferbloat and
implementing airtime fairness in the future.
However some setups (typically low-end platforms
hosting QCA988X) suffer performance regressions
with the current wake_tx_queue implementation.
Therefore disable it unless it is really
beneficial with current codebase (which is when
firmware supports smart pull-push tx scheduling).

In corner case, we may end up processing same interrupt twice.
We have a logic to read pending interrupts at the end of interrupt
processing routine. It has a race with interrupts read in interrupt
handler. This patch solves the problem by ORing the interrupt bitmap
in this case.
The symptom for this bug is below messages in dmesg log.

The sdio dpc starts processing when in SDIOD_STATE_DATA. This state was
entered right after firmware download. This patch moves that transition
just before enabling sdio interrupt handling thus avoiding watchdog

When the host-interface bus has hard time handling transmit packets
it informs higher layer about this and it would stop the netdev
queue when needed. However, since commit 9cd18359d31e ("brcmfmac:

the behaviour is restored.

For multiple REG Host Commands (e.g HostCmd_CMD_802_11_EEPROM_ACCESS,
HostCmd_CMD_MAC_REG_ACCESS etc.) "cpu_to_leX"-converted values are
saved to driver. So, "leX_to_cpu" conversion is required too many
times afterwards in driver.
This patch reduces the endian: conversion without saving "cpu_to_leX"
converted values in driver. This will convert endianness in prepare
command and command response path.

As hw cycle counters in QCA4019 wraparound independantly in QCA4019
it is possible cycle counter and rx clear counter would wraparound

This patch fixes some issues with interface reconfiguration. It could
for example happen that an AP interface in beacon slot 0 was removed
leaving an IBSS station in one of the other slots. When this happens
the driver never sends out the beacon as it only tries to send a beacon
from slot 0.
Appart from that the tracking of required changes to the beacon config is
relatively complicated and prone to errors.
The approach taken here is to solve reconfiguration issues is to
reconfigure the beacons when any interface changes. This means that
the complexity of deciding whether an interface change may modify the
beacon configuration is gone. It also means that the beacon config will
be reliably updated when an interface is removed.
The issue that a single non-AP interface might not be in beacon
slot 0 and wouldn't be send out is solved by moving it into the
first slot. The TSF value in hardware is adjusted accordingly so
that the timestamp of the beacons stay consistent.

The ath9k driver modifies the TSF for VIFs for the purpose of sending
beacons in a staggered fashion. This patch exposes this VIF specific
adjustment of the TSF value to mac80211. Without the change the TSF

seen on the air.

These changes make ath9k_hw_reset more consistent with other places that
handle the TSF value by using the same helper routine.
A slight improvement is to not assume that a fixed time of 1.5ms has
passed for the initval writes when compared to the first write attempt.
Instead the TSF value is re-calculated which will yield a higher accuracy
of the restored TSF timer.

The ath9k TSF handling routines need to be aware of the channel context that
is being modified. With this change the TSF related values that are stored
in each channel context will be correctly tracked and the harware will only
be updated if the modified context is currently the active one.
Without this change the TSF modifications done using these routines would
for example be lost during a hardware reset as done by ath_complete_reset.

Beacons were not send out at (timestamp % beacon_time == 0) for interfaces
other than the primary one. To send out beacons with the correct timestamp
according to 10.1.3.2 of the 802.11 standard the tsf_adjustment has to be
set to the negative time difference instead of positive. This way the
later beacons get corrected to have a lower (and similar) timestamp with
regard to the beacon from slot 0.
I am not aware about any issues that have been caused by this.
