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.
Drop a useless comment as well.

- 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.

- RF2529 fetches default antenna selection from NIC eeprom word
With these assumptions we can change the antenna configuration
to correctly read both antenna setup values and correctly
configure the antenna. And we can now also configure the antenna

mac80211 has 3 values for the antenna setup:
0 - default
1 - use antenna 1
2 - use antenna 2
This means that rt2x00 should store the default value
from the EEPROM somwhere and use that when mac80211 indicates
that the antenna setup is 0.
This also implies that rt2x00 should no longer write the
hw->config.antenna_sel_* values based on the EEPROM input.
This also adds the basis in rt2x00lib for correct software
diversity handling. By default rt2x00lib will now configure
antenna B instead of hardware diversity.

Introduce scan capabilities to WEXT so that userspace can do intelligent
things with scan behavior such as handling hidden SSIDs more gracefully.
If the driver reports a specific scan capability, the driver must
respect the options specified in the iw_scan_req structure when handling
the SIOCSIWSCAN call, unless it's mode or state does not allow it to do
so, in which case it must return an error.
This version switches to Dave Kilroy's suggestion of claiming unused

use the result of the header size modulus 4 as frame
alignment.
Furthermore we shouldn't use NET_IP_ALIGN in rt2x00usb
because it could be 0 on some architectures and we absolutely
need to have 2 bytes reserved for possible aligning.

This fixes Bug #9414
Since addition of the rfkill callback, the LED associated with the off
switch on the radio has not worked for several reasons:
(1) Essential data in the rfkill structure were missing.
(2) The rfkill structure was initialized after the LED initialization.
(3) There was a minor memory leak if the radio LED structure was inited.
Once the above problems were fixed, additional difficulties were noted:
(4) The radio LED was in the wrong state at startup.
(5) The radio switch had to be manipulated twice for each state change.
(6) A circular mutex locking situation existed.
(7) If rfkill-input is built as a module, it is not automatically loaded.
This patch fixes all of the above.

using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in
the kernel.
The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce
more (much more) than a half of all the explicit pid usage.

Because rt2x00 implements the residual calculation different from what the
legacy code does (i.e. scaled values), we need to adjust the residual check.
Again, we are only mimicking the behaviour of the ralink driver without
actually knowing what we do :-(

ipw2100 wasn't sending WEXT scan events at all on scan completion. And
like ipw2200, the driver aggressively auto-scans, requiring
non-user-requested scan events to be batched together and sent at
specific intervals instead of many times per seconds.

Some versions of gcc replace strstr() calls with a single-character `needle'
parameter by strchr() behind our back. This causes a link error if strchr() is
defined as an inline function in <asm/string.h> (e.g. on m68k):
| drivers/built-in.o: In function `libertas_parse_chan':
| linux/drivers/net/wireless/libertas/debugfs.c:209: undefined reference to `strchr'
| drivers/built-in.o: In function `libertas_parse_ssid':
| linux/drivers/net/wireless/libertas/debugfs.c:260: undefined reference to `strchr'
Avoid this by explicitly calling strchr() instead.
Also include <linux/string.h>, because this file calls lots of str*() routines.

Reorganize configuration handling by creating a extra
structure which contains precalculated values based
on the mac80211 values which are usefull for all
individual drivers.
This also fixes the preamble configuration problem,
up untill now preamble was never configured since
by default the rate->val value was used when changing
the mode.
Now rate->val will only be used to set the basic rate mask.
The preamble configuration will now be done correctly
through the erp_ie_changed callback function.
