All existing code which sends commands is set up to have some function

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.

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

Driver support for the monitor mode support that will be available in the next
OLPC 'bleeding edge' Marvell firmware release (most likely, 5.110.16.p2).
To activate monitor mode,
echo mode > /sys/class/net/{ethX,mshX}/device/libertas_rtap
where mode is the hex mask that specifies which frames to sniff (in short, 0x1
for data, 0x2 for all management but beacons, 0x4 for beacons). Any non zero
mode will activate the monitor mode, inhibiting transmission in ethX and mshX
interfaces and routing all the incoming traffic to a new rtapX interface that
will output the packets in 802.11+radiotap headers format.

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.
