If a scan gets aborted BRCMF_SCAN_STATUS_BUSY gets cleared in
cfg->scan_status and when we receive an abort event from the firmware
the BRCMF_SCAN_STATUS_BUSY check in the cfg80211_escan_handler will
trigger resulting in multiple errors getting logged.
Check for a status of BRCMF_E_STATUS_ABORT and in this case simply
cleanly exit the cfg80211_escan_handler. This also avoids a
BRCMF_E_STATUS_ABORT event arriving after a new scan has been started
causing the new scan to complete prematurely without any data.

Using pr_err for things which are not errors is a bad idea. E.g. it
will cause the plymouth bootsplash screen to drop back to the text
console so that the user can see the error, which is not what we
normally want to happen.
Instead add a new brcmf_info macro and use that.

So far we were attaching BRCMF_E_PSM_WATCHDOG event listener in
brcmf_debug_attach which gets compiled only with CONFIG_BRCMDBG. This
event means something went wrong and firmware / hardware usually can't
be expected to work (reliably).
Such a problem is significant for user experience so I believe we should
print an error unconditionally (even with debugging disabled). What can
be indeed optional is dumping bus memory as this is clearly part of
debugging process.
In the future we may also try to extend this listener by trying to
recover from the error or at least signal it to the cfg80211.

We observed a SHUTDOWN command timeout during reboot stress test due to
a corner case firmware bug. It can lead to either a use-after-free +
OOPS (on either the adapter structure, or the 'card' structure) or an
abort (where, e.g., the PCI device is "disabled" before we're done
dumping the FW).
We can avoid this by canceling/flushing the FW dump work:
(a) after we've terminated all other work queues (e.g., for processing
commands which could time out)
(b) after we've disabled all interrupts (which could also queue more
work for us)
(c) after we've unregistered the netdev and wiphy structures (and
implicitly, and debugfs entries which could manually trigger FW dumps)
(d) before we've actually disabled the device (e.g.,
pci_device_disable())
Altogether, this means no card->work will be scheduled if we sync at
a point that satisfies the above. This can be done at the beginning of
the .cleanup_if() callback.

Channels 34/38/42/46 can only be used for compatibility with old devices sold
in Japan. Modern products, such as AR6003/AR6004 don't support these channels.
Keeping them in the upstream is error prone and requires full network stack
support. A custom patch should be used in case such compatibility is required.
Without this one, a user is able to start an AP using wpa_supplicant,
for example, on one of these channels (34/38/42/46), without getting
any warning/error from the cfg80211 or ath6kl - which is correct
(since these channels match regdom rules). However, the AR6003 and its

If a 5 GHz radio is calibrated for operation in both
the low band (channels 36 to 64) and high band(channels 100 to 169),
hardware allows operations in all the listed channels. However,
if the chip has been calibrated only for the low/high band and
a high/low band channel is configured, due to lack of calibration
there will be potentially invalid signal on those non calibrated channels.
To avoid this problem this patch sets IEEE80211_CHAN_DISABLED flag for
those non calibrated channels by using low_5ghz_chan and high_5ghz_chan
values which we get from target through wmi service ready event.
Driver initialized flags are getting re initialized in handle_channel
in cfg80211. So calling the function to disable the non supported channel

In a fast disconnect/connect sequence, cfg80211_connect_result() can
fail to find the bss object which the driver is connecting to. Detailed
sequence of events:
* Driver is connected in STA mode
* Disconnect request arrives from user space. Driver disconnects and
calls cfg80211_disconnected() which adds new event to the
cfg80211_wq worker thread
* Connect request arrives from user space. cfg80211_connect() stores
ssid/ssid_len and calls rdev_connect()
* __cfg80211_disconnected() runs in worker thread and zero
wdev->ssid_len
* Connect succeeds. Driver calls cfg80211_connect_result() which fails
to find the bss because wdev->ssid_len is zero
To overcome this, upon connect request, store the bss object in the
driver and upon connect completion pass it to kernel using

Len Brown reported the system resume time is taking more than 2 seconds in
bug - https://bugzilla.kernel.org/show_bug.cgi?id=185621.
The reason of the 2 seconds is due to the firmware download time.
The chip is booted up in the default reference clock speed to handle the
firmware download to chip memory and advanced to the support higher speed
clock to run the firmware after all. The default reference clock in the
hardware is slow so that the firmware download time is taking up to 2
seconds for a 600KB firmware file.

[76798.334612] ath10k_pci : htt tx max num pending tx 1056
The resolution here is to enable the higher speed clock if the hardware
supported before the firmware download at BMI stage, so that the hardware
can handle the firmare download in a more efficient way. This can help to
improve the firmware download time from 2 seconds to around 500ms for the
same 600KB firmware file.

The steps to advance to the higher speed clock is very hardware specific,
so adding the hardware ops for the hardware that can support this.

The rtl8187 cards don't seem to receive multicast frames, which,
among other things, makes them fail to receive RAs in IPv6 networks.
The cause seems to be that the RTL818X_RX_CONF_MULTICAST flag doesn't
have the desired effect.
Fix the issue by setting RTL818X_RX_CONF_MONITOR instead, which puts the
card into monitor mode and resolves the problem so that multicast frames
are sucessfully passed to the kernel.
The existence of the problem and the effectiveness of the solution has
originally been confirmed on an 8187B based card with the USB id of
0bda:8197. Subsequent testing by Larry Finger on an 8187L based card,
which follows the second (8187, i.e. "non-b") code path in the driver,
has confirmed that the fix does not cause any noticeable regresssions
there either.

Even if we do not set AMPDU bit in TXWI, device still can aggregate
frame and send it with rate not corresponding to requested. That mean
we can do not sent probe frames with requested rate. To prevent that
use TXOP_BACKOFF for probe frames.

We use skb_desc->tx_rate_flags from entry as rate[].flags even if
skb does not match status. Patch corrects flags and also fixes
mcs for legacy rates.
rt2800_rate_from_status() is based on Felix's mt76
mt76x2_mac_process_tx_rate() function.

If we do not match skb entry, provide tx status via nomatch procedure.
Currently in that case we do rt2x00lib_txdone_noinfo(TXDONE_NOINFO),
which actually assume that entry->skb was posted without retries and
provide rate saved in skb desc as successful. Patch changed that to
rate read from TX_STAT_FIFO, however still do not provide correct
number of retries.
On SoC/PCI devices we keep providing status via standard txdone
procedure, no change in those devices, though we should thing about it.

Add bits rt2x00lib_fill_tx_status() when filling status in nomatch
case and hopefully do not break the function for existing cases.
