are completely useless for me. Remove bunch of code that generate them.

dd6d2a8aef iwlegacy: remove reset rf infrastructure

22450902e4 iwlegacy: remove sync_cmd_mutex
We now use priv->mutex to serialize sync command, remove old
priv->sync_cmd_mutex and add assertion that priv->mutex must be locked.

28a6e577c6 iwlegacy: more priv->mutex serialization
Check status bits with mutex taken, because when we wait for mutex
unlock, status can change. Patch should also make remaining sync
commands be send with priv->mutex taken. That will prevent execute
these commands when we are currently reset firmware, what could
possibly cause troubles.

332704a514 iwlegacy: fix tx_power initialization
priv->tx_power_next is not initialized to max supported power,
but instead default value is used, what cause errors like

[   58.597834] iwl3945 0000:03:00.0: Requested user TXPOWER 15 above upper limit 14.
[   58.597839] iwl3945 0000:03:00.0: Error setting Tx power (-22).

if maximum tx power read from the eeprom is smaller than default.
In consequence card is unable to initialize properly. Fix the problem
and cleanup tx power initialization.

0263aa4529 iwl3945: disable hw scan by default
After new NetworkManager 0.8.996 changes, hardware scanning is causing
microcode errors as reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=683571
and sometimes kernel crashes:
https://bugzilla.redhat.com/show_bug.cgi?id=688252

Also with hw scan there are very bad performance on some systems
as reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=671366

Since Intel no longer supports 3945, there is no chance to get proper
firmware fixes, we need workaround problems by disable hardware scanning
by default.

7bb4568372 mac80211: make tx() operation return void
The return value of the tx operation is commonly
misused by drivers, leading to errors. All drivers
will drop frames if they fail to TX the frame, and
they must also properly manage the queues (if they
didn't, mac80211 would already warn).

Removing the ability for drivers to return a BUSY
value also allows significant cleanups of the TX
TX handling code in mac80211.

Note that this also fixes a bug in ath9k_htc, the
old "return -1" there was wrong.

be663ab670 iwlwifi: split the drivers for agn and legacy devices 3945/4965
Intel WiFi devices 3945 and 4965 now have their own driver in the folder

	drivers/net/wireless/iwlegacy

Add support to build these drivers independently of the driver for
AGN devices. Selecting the 3945 builds iwl3945.ko and iwl_legacy.ko,
and selecting the 4965 builds iwl4965.ko and iwl_legacy.ko. iwl-legacy.ko
contains code shared between both devices.

The 3945 is an ABG/BG device, with no support for 802.11n. The 4965 is a 2x3
ABGN device.
