2abdc0b775 libertas: kill internal tx queue for PS mode
It was buggy as hell anyway, since it was just spewing packets at the
device when it wasn't necessarily ready for them (in the USB case, while
the URB was still busy).

We could probably do with a better way of flushing packets to the device
_immediately_, before we stick it back into sleep mode. But we can no
longer just dequeue packets directly, it seems.

448a51ae06 libertas: switch lbs_cmd() to take a callback function pointer
All existing code which sends commands is set up to have some function
called with the results, not to get data back. It's more versatile this
way, and providing it with a callback function which involves memcpy()
is hardly difficult.

675787e29f libertas: handy function to call firmware commands
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:

0d61d04210 libertas: make more functions static
These functions were used in the old debugfs code for events, but

e775ed7c67 libertas: Consolidate lbs_host_to_card_done() function.
As we move towards having this done by a state machine, start by having
a single 'stuff sent' function, which is called by if_usb/if_sdio/if_cs
after sending both data and commands.

1007832103 libertas: move to uniform lbs_/LBS_ namespace
This patch unifies the namespace of variables, functions defines
and structures. It does:

- rename libertas_XXX to lbs_XXX
- rename LIBERTAS_XXX to lbs_XXX
- rename wlan_XXX to lbs_XXX
- rename WLAN_XXX to LBS_XXX (but only those that were
  defined in libertas-local *.h files, e.g. not defines
  from net/ieee80211.h)

While passing, I fixed some checkpatch.pl errors too.

954ee164f4 [PATCH] libertas: reorganize and simplify init sequence
This patch moves all firmware load responsibility into the interface-specific
code and gets rid of the firmware pointer in the generic card structure.  It
also removes 3 fairly unecessary callbacks: hw_register_dev, hw_unregister_dev,
and hw_prog_firmware.  It also makes the init sequence from interface
probe functions more logical, as there are paired add/remove and start/stop
calls into generic libertas code.

Because the USB driver code uses the same TX URB callback for both firmware
upload (where the generic libertas structure isn't initialized yet) and for
normal operation (where it is), some bits of USB code have to deal with
'priv' being NULL.  All USB firmware upload bits have been changed to not
require 'priv' at all, but simply the USB card structure.

1df4e8fe91 [PATCH] libertas: remove fw.c
Firmware download is quite different for different hardware. The SDIO and CF
cards have two flat files that need to be downloaded, whereas the USB driver
needs only one file, but with an internal structure.

The code that handles this (USB only) structured file is currently in fw.c.
This patch moves this code into if_usb.c. The remaining functions in fw.c
have not much to do with firmware, they are various card- and network-stack
initialisation functions. I've moved them into main.c.

8c51276575 [PATCH] libertas: simplify and clean up data rate handling
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.

32a74b7c8f [PATCH] libertas: split wlan_add_card()
Split wlan_add_card() into a part that just setups kernel parameters and
into the function libertas_activate_card(), which will implizitly use
hardware functions by the started thread.

This allows us later to do something like this:

priv = libertas_add_card();
priv->hw_command_to_host = if_usb_command_to_host;
priv->hw_xxxx = if_usb_xxxx;
priv->hw_yyyy = if_usb_yyyy;
wlan_activate_card()

and of course the CF driver can set it's own functions.

In libertas_process_rxed_packet() and process_rxed_802_11_packet() the
skb is dereferenced after being passed to netif_rx (called from
libertas_upload_rx_packet). Spotted by Coverity (1658, 1659).

Also, libertas_upload_rx_packet() unconditionally returns 0 so the error
check is dead code - might as well take it out and change the signature.
