David Gnedt b90a1165a7 wl1251: enforce changed hw encryption support on monitor state change
The firmware doesn't support per packet encryption selection, so disable hw
encryption support completely while a monitor interface is present to support
injection of packets (which shouldn't get encrypted by hw).
To enforce the changed hw encryption support force a disassociation on
non-monitor interfaces.
For disassociation a workaround using hw connection monitor is employed,
which temporary enables hw connection manager flag.

David Gnedt ed3213c913 wl1251: fix channel switching in monitor mode
Use the ENABLE_RX command for channel switching when no interface is present
(monitor mode only).
The advantage of ENABLE_RX is that it leaves the tx data path disabled in
firmware, whereas the usual JOIN command seems to transmit some frames at
firmware level.

David Gnedt 64322e28d3 wl1251: fix scan behaviour while not associated
With a dissasociated card I often encoutered very long scan delays.

My guess is that it has something to do with the cards DTIM handling and
another firmware bug mentioned in the TI WLAN driver, which is described as
the card may never end scanning if the channel is overloaded because it
can't send probe requests. I think the firmware somehow also tries to
receive DTIM messages when the BSSID is not set. Therefore most of the time
it waits for DTIM messages and can't do scanning work.

Anyway we can workaround this misbehaviour by setting the HIGH_PRIORITY
bit for scans in disassociated state.

The destructor for net devices was set to free_netdev() to get rid
of it and the private data. The private data refers to a brcmf_if
instance, but indirectly it also refers to brcmf_cfg80211_vif which
holds the wdev. This is freed as well by using a new custom destructor
called brcmf_cfg80211_free_netdev().

Currently, the MAC context tsf_id assignment and the master/slave
relations are determined only when a new vif is added, as part
of the MAC context resource allocation. However, at this stage, the
beacon interval is not known, and thus could not be taken into account
in the master-slave algorithm.

To fix this, recalculate the MAC context tsf_id assignment,
just before the MAC context is activated, i.e., just before
a station VMAC is configured to associated and before an AP
VMAC is started.

The firmware needs to be stopped quickly (100ms) after the
RFKILL interrupt fired. Failing to do so would allow the
firmware to access the radio registers which would lead to
a hardware error.

Before this change, we would kill the firmware only when
mac80211 stops the device which can take a fair amount of
time. Take a shortcut by stopping the device right away
in the interrupt.

This is not relevant if the current firmware is INIT
firmware since that firmware can run while in RFKILL.

Emmanuel Grumbach 3dc3374fce iwlwifi: pcie: don't update the op_mode if rfkill hasn't changed
This is useless and introduces a dependency between rfkill
and stop_device - the op_mode can't call stop_device from
the rfkill notification since it would lead to an endless
recursion.
Next patches will need to do so.

Emmanuel Grumbach b943949105 iwlwifi: pcie: keep the NIC awake when commands are in flight
Under very specific circumstances, the firmware might
ignore a host command. This was debugged and we ended up
seeing that the power management hardware was faulty.
In order to workaround this issue, we keep the NIC awake
as long as we have host commands in flight. This will avoid
to put the hardware into buggy condition.

Emmanuel Grumbach 3dd94794a9 iwlwifi: mvm: fix AC / FIFO mapping
The AC / fifo mapping was wrong - BE packets landed in VO
FIFO. The iwl_mvm_tx_fifo enumeration isn't in the same
order as ieee80211_ac_numbers enumeration.
Since the firmware relies on fifo / ac mapping - this led
to wrong behavior. E.g. the firmware sends beacon with the
same QoS parameters as VO, and it actually took the
parameters of BK. There are probably more severe issues.

The payload of the QoS Map Set element (IEEE Std 802.11-2012, 8.4.2.97)

configure the local behavior either on the AP (based on local

Rashika Kheria 03a71e0328 drivers: net: Mark functions as static in 3945-debug.c
This patch marks the function il3945_ucode_rx_stats_read(),
il3945_ucode_tx_stats_read() and il3945_ucode_general_stats_read() in
3945-debug.c as static because they are not used outside this file.

Bing Zhao 82efa16ad2 mwifiex: download per country tx power table to firmware
When driver gets regulatory domain change notifications or before
associates to an AP with Country IE, the txpwrlimit table stored
in device tree for that country is downloaded to firmware.

The txpwrlimit downloading will happen only at the first time
when the alpha2 country code is changed. World regulatory domain
"00" notification doesn't trigger the downloading. This behavior
is same as domain_info command.

Bing Zhao 699b027b9c mwifiex: download cal-data from device-tree to firmware
Currently only conf file based cal-data downloading is supported.
On embedded platforms a better place to store the cal-data is in
device tree. Add cal-data downloading from device tree to firmware.
Both methods can co-exist.

Bing Zhao dd4a9ac05c mwifiex: send regulatory domain info to firmware only if alpha2 changed
On cfg80211 regulatory domain change, drivers gets alpha2 country
code or "00" in driver's notification handler.

In most cases, the pattern will be US, 00, US, 00, US, 00, US, ...
There is no need to send domain info to firmware in case of "00" or
with the same alpha2 country code.

Arend van Spriel 36c4e7e4aa brcmfmac: clarify struct brcmf_sdio_dev::func[0] reference
The struct brcmf_sdio_dev contains array of sdio functions that
are used in the driver. However, during probe func[0] entry was
assigned to the function 1 reference. This was corrected upon
doing the actual I/O access. This patch makes it more clear by
creating the func[0] entry properly and use it as is during
I/O access.
