% echo 0x00000FFO > /proc/net/ieee80211/debug_level
For a list of values you can assign to debug_level, you
- can look at the bit mask values in <net/ieee80211.h>
+ can look at the bit mask values in ieee80211.h
If you are not trying to debug or develop the libipw
component, you most likely want to say N here.
