354eca9820 libertas: submit RSSI command on tx timeout, to check whether module is dead
We don't necessarily want to reset the device on a TX timeout. But more
often than not, the real cause is that the firmware has crapped itself,
not just that the network is busy. So submit any harmless command, and
if _that_ times out, then the error handling code will reset the module,
as appropriate.

18c52e7c3e libertas: make lbs_submit_command always 'succeed' and set command timer
Even if it fails, we want to wait a while and try again, with an
ultimate timeout if it the condition persists. So again, just use the
standard command timeout behaviour.

8538823f7c libertas: discard DEFER responses to commands; let the timeout trigger
When the firmware returns 0x0004, it wants us to try again later. We can
achieve that simply by throwing out the response and letting the command
timeout code kick in.

If we don't scribble over the command we sent, then we can retry it when

b2c57eee66 libertas: allow for PS mode to be disabled when firmware doesn't support it
Otherwise, we go into an endless busy loop trying to enable PS mode when
the command queue is empty, dealing with the error response, and then
trying to enable PS mode again because the command queue is empty.... it
doesn't really save much power.

24dba5f391 libertas: don't clear priv->dnld_sent after sending sleep confirm
DNLD_RES_RECEIVED is a bit of a misnomer -- we never wait for the result
to be received; it's purely representing the state of the TX path, and
in this case the TX path is definitely busy.

Of course, that means that we don't actually care about DATA_SENT vs.
CMD_SENT either, but that's a can of worms for another day...

38bfab1a01 libertas: fix buffer handling of PS_MODE commands and responses
Commit 5b8845345e7385d2eb37fac22ba9ab6905988be5 (or, in case the git
workflow is broken and patches get recommitted, the commit entitled
'libertas: rename and re-type bufvirtualaddr to cmdbuf' by dcbw),
introduced a number of bugs where we once had a pointer to a command
_payload_, but now we use the pointer to the command header instead.

The fix isn't wonderfully pretty for now, but it'll get better when we
finish converting all commands so the structures include the header.

4ad36d780c b43legacy: Fix rfkill radio LED
This fixes Bug #9414 for b43legacy. This patch is the equivalent of one
submitted earlier for b43.

Since addition of the rfkill callback, the LED associated with the off
switch on the radio has not worked for several reasons:

(1) Essential data in the rfkill structure were missing.
(2) The rfkill structure was initialized after the LED initialization.
(3) There was a minor memory leak if the radio LED structure was inited.

Once the above problems were fixed, additional difficulties were noted:

(4) The radio LED was in the wrong state at startup.
(5) The radio switch had to be manipulated twice for each state change.
(6) A circular mutex locking situation existed.
(7) If rfkill-input is built as a module, it is not automatically loaded.

This patch fixes all of the above and removes a couple of sparse warnings.

little-endian, not the other way round).
* bug: setup_hw_rings() should not convert to little-endian at all (we
feed the result to writel(), not store in shared data structure), let
alone try to play with shifting and masking little-endian values.  Introduced
when setup_hw_rings() went in, screwed both 64bit case and the old code for

f3ec33e587 sunhme endianness annotations
This one is interesting - SBUS and PCI variants have
opposite endianness in descriptors (SBUS is sparc-only, so there
host-endian == big-endian).

	Solution: declare a bitwise type (hme32) and in accessor
helpers do typechecking and force-casts (once we know that the
type is right).
