f15ebb63b3 libertas: change inference about buffer size in lbs_cmd()
sizeof(*cmd) is going to give the total size of the data structure that
we allocated, more often than not. But the size of the command to be
_sent_ could be a lot smaller, as it is in the KEY_MATERIAL and
SUBSCRIBE_EVENT commands for example. So swap them round; let the caller
set the _command_ size explicitly in the header, and infer the
maximum response size from the data structure.

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.

8538823f7c libertas: discard DEFER responses to commands; let the timeout trigger

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.

0f1c8232e8 libertas: remove casts from lbs_cmd() and lbs_cmd_with_response() macros
If stupid people like me give it arguments with the wrong type (like a
pointer to the structure, for example, instead of the structure itself),
then we should probably notice that at compile time. Otherwise, much
confusion ensues.

Firstly, they set the frame type, which isn't necessary since
lbs_hard_start_xmit() gets to see which device it belongs to anyway.

Secondly, they return -EOPNOTSUPP if the device is in monitor mode.
Which is a strange thing to do and will provide nasty warnings from
qdisc_restart(). And lbs_hard_start_xmit() seems to have code to cope
with monitor mode anyway.
