There seems to be no point in doing it as an ieee80211 device instead of
a normal netdev, and when we override its ->priv and then call
free_ieee80211() it has a distressing tendency to crash horribly.

These wrappers only do two things.
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.

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.

This changes the code that is used for scanning and makes it hopefully
easier to understand:
* move function into logical blocks
* create a bunch of lbs_scan_add_XXXX_tlv() functions, that
help to create the TLV parameter of CMD_802_11_SCAN
* all of them are now called from the much simpler lbs_do_scan()
* no **puserscancfg double-pointers :-)

It says "I have 20 bytes", I take 20 bytes, but the last 8 bytes of this

Also, in the new lbs_cmd() where was a size miscalulation

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

1) Do not reset libertas devices upon module unload. We're unloading
the module, we're not killing off devices.
2) Instead, reset libertas devices inside if_usb_disconnect, as we're
killing off interfaces and so on.
3) Resetting via disconnect callback means we no longer need to keep
track of probed libertas devices; kill off that list (and its wonderful
lack of locking..), as well.
