Recently I found that that sparse by default doesn't endianness
checks. So I changed my compilation habit to be
make modules C=1 SUBDIRS=drivers/net/wireless/libertas
CHECKFLAGS="-D__CHECK_ENDIAN__"
so that I get the little-endian checks from sparse as well. That
showed up a good bunch of problems.

I wondered about junk bytes at the end when using "lbsdebug +hex +host"
until I noticed that firmware for the CF card sends my extranous bytes.
It says "I have 20 bytes", I take 20 bytes, but the last 8 bytes of this
are just data junk.
Also, in the new lbs_cmd() where was a size miscalulation
that made itself clear after fixing this bug.

Using an arbitrary firmware command was actually very painful. One
had to change big switch() statements in cmd.c, cmdresp.c, add
structs to the big union in "struct cmd_ds_command" and add the
define for the CMD_802_11_xxx to the proper place.
With this function, this is now much easier. For now, it implements
a blocking (a.k.a. CMD_OPTION_WAITFORRSP) way where one deals directly
with command requests and response buffers. You can do everything in
one place:

This patch moves re-works the implementation of event subscription
via debugfs. For this:
* it tells cmd.c and cmdresp.c about CMD_802_11_SUBSCRIBE_EVENT
* removes lots of low-level cmd stuff from debugfs.c
* create unified functions to read/write snr, rssi, bcnmiss and
failcount
* introduces #define's for subscription event bitmask values
* add a function to search for a specific element in an IE
(a.k.a. TLV)
* add a function to find out the size of the TLV. This is needed
because lbs_prepare_and_send_command() has an argument for a
data buffer, but not for it's lengths and TLVs can be, by
definition, vary in size.
* fix a bug where it was not possible to disable an event

any iwconfig commands on the main interface.

Test case 2: Associate with the main interface, and turn off AP. Mesh
interface should not lose connectivity.
$ iwconfig eth0 mode managed essid "my_ssid"

types.h contains the same amount of CMD_RET_xxx and CMD_xxx definitions.
They contains the same info: the firmware command opcode and, when the
firmware sends back a result, the command opcode ORed with 0x8000.
Having the same data twice in the source code is redundant and can lead to
errors (e.g. if you update or delete only one instance). This patch removed
all CMD_RET_xxx definitions and introduces a simple CMD_RET() macro.

Currently, when you define LBS_DEB_HEX, you get every hex dump in the
whole driver, e.g. for LBS_DEB_CMD, LBS_DEB_RX, LBS_DEB_TX etc. This
patch makes sure that you only get the hexdump that you're interested in.
Renamed lbs_dbg_hex() into lbs_deb_hex(), like the other lbs_deb_XXX()
macros.
Made lbs_deb_hex() issue a line feed (and a new prompt) after 16 bytes.
As lbs_deb_hex() now prints the ":" after the prompt by itself, removed
the misc colons in the various *.c files.
lbs_deb_XXX() now print the debug category as well.
As lbs_deb_XXX() --- and especially lbs_deb_11d() --- now print the
category, I removed various "11D:" prefixes in 11d.c as well.

Remove unused/duplicated fields and consolidate static data rate arrays,
for example the libertas_supported_rates[] and datarates[] arrays in
the bss_descriptor structure, and the libertas_supported_rates field
in the wlan_adapter structure.
Introduce libertas_fw_index_to_data_rate and libertas_data_rate_to_fw_index
functions and use them everywhere firmware requires a rate index rather
than a rate array.
The firmware requires the 4 basic rates to have the MSB set, but most
other stuff doesn't, like WEXT and mesh ioctls. Therefore, only set the MSB
on basic rates when pushing rate arrays to firmware instead of doing a ton
of (rate & 0x7f) everywhere.

The BSS to associate with (in either Infrastructure or IBSS join
operations) is now stored in _one_ place in the association request (the
bss member), not two places as before (pattemptedbss and
curbssparams->bssdescriptor).
Association requests are passed to the necessary association functions
to (a) give them access to the bss member and (b) ensure that
association/join/start setup uses settings from the request, not the
current adapter settings (which may not be valid for the requested
settings).
Because the 'bss' member of the association request is used now, the
command return functions from associate and adhoc join/start need access
to the in-progress association request to update curbssparams when
everything is done. The association worker moves the request from
pending to in-progress for the duration of the association attempt.

Actually, this patch removev wlan_dev_t totally and puts the used variables
of it directly into wlan_private. That reduces one level of indirection and
looks a little bit simpler. It's now "priv->card" and not
"priv->wlan_dev.card" and "priv->dev" instead of "priv->wlan_dev.netdev"
Changed two occurences of "((wlan_private *) dev->priv)->wlan_dev.netdev"
