Now uses __lbs_cmd() to get the "log" (it's actually more a snapshot of
various counters, not a sequential log). Besides the "mechanical" convertion
the patch add the following logical changes:
* Removes the priv->logmsg variable, it was only used in one place anyway,
also don't blindly get the counters when associating. Getting the
counters then the user asks via WEXT for them is good enought.
* don't set wstats.discard.fragment with log.rxfrag, because the latter is
a counter for successfully received packets, not for fragmented packets.

This uses a static lbs_cmd_async_callback function, which is a
noop. Just setting the callback argument to __lbs_cmd_async()
to NULL won't work, because then the cmdnode wouldn't be
released.
This also makes __lbs_cmd_async() a static method, which is
now only used by lbs_cmd() and lbs_cmd_async().

The iwlxxxx_pci_remove functions are not needed when drivers are not
compiled as modules - they can thus be discarded at kernel link time.
This is already captured by having them as __devexit_p in the pci_driver
struct - these are supposed to be pointers to __devexit functions, but was not.
This is now fixed.
This problem was reported by Toralf Forster when testing the compilation of
2.6.25-rc6.

Indirect scanning ('iwlist scan') should report information about

After sampling hundreds of RX frame descriptors,
the results were conclusive:
- The Ralink documentation regarding the SIGNAL and RSSI are wrong.
It turns out that of the 5 BBR registers, we should not use BBR0 and BBR1
for SIGNAL and RSSI respectively, but actually BBR1 and BBR2.
BBR0 does show values, but the exact meaning remains unclear,
but they cannot be translated into a SIGNAL or RSSI field.
BBR3, BBR4 and BBR5 are always 0, so their meaning is unknown.
As it turns out, the reported SIGNAL is the PLCP value, this
in contradiction to what was expected looking at rt2500pci which
only reported the PLCP values for OFDM rates and bitrate values
for CCK rates.
This means we should let the driver raise the flag about the contents
of the SIGNAL field so rt2x00lib can always do the right thing based
on what the driver reports.

The basic rate which is configured in the register
should not match all supported rates, but only the _basic_ rates.
Fix this by adding a new flag to the rt2x00_rate structure

When mac sets the IEEE80211_TXCTL_SEND_AFTER_DTIM flag, we should
check if the ATIM queue is available in the driver and put the
frame in that queue for proper behavior (send frame after beacon interval).

rt2x00lib should filter SW diversity out before sending any configuration
changes to the driver. When rt2x00lib fails to do this, it is important

rt2x00lib depended on 2 crc algorithms because rt61/rt73
use a different algorithm then rt2800. This means that
even when only 1 algorithm was needed, the dependency was
still present for both.
By moving the checksum generation to the driver we can clean
up 2 annoying flags (which indicated which checksum was required)
and move the dependency to where it belongs: the driver.

We should not write 0 to the beacon sync register during
config_intf() since that will clear out the beacon interval
and forces the beacon to be send out at the lowest interval.
(reported by Mattias Nissler).
The side effect of the same bug was that while working with
multiple virtual AP interfaces a change for any of those
interfaces would disable beaconing untill an beacon update
was provided.
This is resolved by only updating the TSF_SYNC value during
config_intf(). In update_beacon() we disable beaconing
temporarily to prevent fake beacons to be transmitted.
Finally kick_tx_queue() will enable beaconing again.
