 	---help---
-	  This option will enable debug tracing output for the IPW2200.  
+	  This option will enable low level debug tracing output for IPW2200.
 
-	  This will result in the kernel module being ~100k larger.  You can 
-	  control which debug output is sent to the kernel log by setting the 
-	  value in 
-
-	  /sys/bus/pci/drivers/ipw2200/debug_level
-
-	  This entry will only exist if this option is enabled.
+	  Note, normal debug code is already compiled in. This low level
+	  debug option enables debug on hot paths (e.g Tx, Rx, ISR) and
+	  will result in the kernel module being ~70 larger.  Most users
+	  will typically not need this high verbosity debug information.
 
-	  To set a value, simply echo an 8-byte hex value to the same file:
-
-	  % echo 0x00000FFO > /sys/bus/pci/drivers/ipw2200/debug_level
-
-	  You can find the list of debug mask values in 
-	  drivers/net/wireless/ipw2200.h
-
-	  If you are not trying to debug or develop the IPW2200 driver, you 
-	  most likely want to say N here.
+	  If you are not sure, say N here.

-/*    *** THEORY OF LOCKING ***
- *
- * We have two different locks in the bcm43xx driver.
- * => bcm->mutex:    General sleeping mutex. Protects struct bcm43xx_private
- *                   and the device registers.
- * => bcm->irq_lock: IRQ spinlock. Protects against IRQ handler concurrency.
- *
- * We have three types of helper function pairs to utilize these locks.
- *     (Always use the helper functions.)
- * 1) bcm43xx_{un}lock_noirq():
- *     Takes bcm->mutex. Does _not_ protect against IRQ concurrency,
- *     so it is almost always unsafe, if device IRQs are enabled.
- *     So only use this, if device IRQs are masked.
- *     Locking may sleep.
- *     You can sleep within the critical section.
- * 2) bcm43xx_{un}lock_irqonly():
- *     Takes bcm->irq_lock. Does _not_ protect against
- *     bcm43xx_lock_noirq() critical sections.
- *     Does only protect against the IRQ handler path and other
- *     irqonly() critical sections.
- *     Locking does not sleep.
- *     You must not sleep within the critical section.
- * 3) bcm43xx_{un}lock_irqsafe():
- *     This is the cummulative lock and takes both, mutex and irq_lock.
- *     Protects against noirq() and irqonly() critical sections (and
- *     the IRQ handler path).
- *     Locking may sleep.
- *     You must not sleep within the critical section.
