While the comment removed in this patch claims board_n800.c uses
"cx3110x", it was never merged to mainline like this. Mainlined board
files for Nokia N8x0 devices are expected "p54spi", and thus don't
work because the modalias is "cx3110x". To my knowledge, these
devices are the only real-world use of p54spi, and will not work
without this change. Tested against my Nokia N810.

Commit 56d1de0a21, "ath5k: clean up
filter flags setting" introduced a regression in monitor mode such
that the promisc filter flag would get lost.
Although we set the promisc flag when it changed, we did not
preserve it across subsequent calls to configure_filter. This patch
restores the original functionality.

Because there is a limited number of tx buffers available, once the
queue has been filled to a certain point, ath9k needs to stop accepting
new frames from mac80211. In order to prevent a full WMM queue from
stopping another queue with fewer frames, this patch limits the number
of queued frames to a quarter of the total available tx buffers, minus
some reserved frames to be used for other purposes (e.g. beacons).
Because tx buffers are reserved for frames when they're staged in
software queues as well, the actual queue depth cannot be used for
this, so this patch stores a reference to the tx queue in the ath_buf
struct and keeps track of the total number of pending frames.

This patch revamps IDLE power save handling in the driver.
Two separate functions (radio enable/disable) are introduced,
because the semantics of radio handling is just not the same
as the start()/stop() callbacks. For example, the HW must not
be disabled, instead, the PHY has to be disabled in radio_disable().
Also, the HW has to be reset properly in radio enable/disable and
certain registers have to be programmed only once, in the
start() callback.
The radio_enable() routine doesn't need the PS wrappers since
we set the HW power mode to AWAKE anyway before calling it.

The snprintf() function returns the number of bytes that *would* have
been written (not counting the NULL terminator) and that can potentally
be more than the size of the buffer.
In this patch if there were one liners where string clearly fits into
the buffer, then I changed snprintf to sprintf(). It's confusing to use
the return value of snprintf() as a limitter without verifying that it's
smaller than size. This is what initially caught my attention here.
If we use the return value of sprintf() instead future code auditors will
assume we've verified that it fits already.
Also I did find some places where it made sense to use the return value
after we've verified that it is smaller than the buffer size.
Finally the read_file_rcstat() function added an explicit NULL terminator
before calling snprintf(). That's unnecessary because snprintf() will
add the null terminator automatically.

By calling korina_restart(), the IRQ handler tries to disable the
interrupt it's currently serving. This leads to a deadlock since
disable_irq() waits for any running IRQ handlers to finish before
returning. This patch addresses the issue by turning korina_restart()
into a workqueue task, which is then scheduled when needed.
Reproducing the deadlock is easily done using e.g. GNU netcat to send
large amounts of UDP data to the host running this driver.
Note that the same problem (and fix) applies to TX FIFO underruns, but
apparently these are less easy to trigger.
