The driver should delay only in recording stop flow between writing to
DBGC_IN_SAMPLE register and DBGC_OUT_CTRL register. Any other delay is
not needed.
Change the following:
1. Remove any unnecessary delays in the flow
2. Increase the delay in the stop recording flow since 100 micro is
not enough
3. Use usleep_range instead of delay since the driver is allowed to
sleep in this flow.

In some buggy scenarios we could possible attempt to transmit frames larger
than maximum MSDU size. Since our devices don't know how to handle this,
it may result in asserts, hangs etc.
This can happen, for example, when we receive a large multicast frame
and try to transmit it back to the air in AP mode.
Since in a legal scenario this should never happen, drop such frames and
warn about it.

- OEM will change WGDS revision to 1 (currently latest revision is 0)

- Driver will read the WGDS table and pass the values to FW (as usual)

This change fixes a rare race condition of handling WMI events after
wmi_call expires.
wmi_recv_cmd immediately handles an event when reply_buf is defined and
a wmi_call is waiting for the event.
However, in case the wmi_call has already timed-out, there will be no
waiting/running wmi_call and the event will be queued in WMI queue and
will be handled later in wmi_event_handle.
Meanwhile, a new similar wmi_call for the same command and event may
be issued. In this case, when handling the queued event we got WARN_ON
printed.
Fixing this case as a valid timeout and drop the unexpected event.

In the old days (linux 2.6 and early 3.x), the parse_txq_params()

This patch follows Alan Stern's recent patch:
"p54: Fix race between disconnect and firmware loading"
that overhauled carl9170 buggy firmware loading and driver
unbinding procedures.
Since the carl9170 code was adapted from p54 it uses the
same functions and is likely to have the same problem, but
it's just that the syzbot hasn't reproduce them (yet).
a summary from the changes (copied from the p54 patch):
* Call usb_driver_release_interface() rather than
device_release_driver().
* Lock udev (the interface's parent) before unbinding the
driver instead of locking udev->parent.
* During the firmware loading process, take a reference
to the USB interface instead of the USB device.
* Don't take an unnecessary reference to the device during
probe (and then don't drop it during disconnect).
and
* Make sure to prevent use-after-free bugs by explicitly
setting the driver context to NULL after signaling the
completion.

the lower bound of RX packets was set to 10 (min ACK size) to

Alas, short radar pulses are reported as PHY_ERROR frames
with length set to 3. Therefore their detection stopped
working after that commit.
NOTE: ath9k drivers built thereafter will not pass DFS
