config IEEE80211

---help---
2005-07-31 17:05:43 +00:00
This option enables the hardware independent IEEE 802.11
networking stack.
config IEEE80211_DEBUG
bool "Enable full debugging output"
depends on IEEE80211
---help---
2005-07-31 17:05:43 +00:00
This option will enable debug tracing output for the
ieee80211 network stack.
2005-07-31 17:05:43 +00:00
This will result in the kernel module being ~70k larger. You
can control which debug output is sent to the kernel log by
setting the value in
/proc/net/ieee80211/debug_level
For example:
% echo 0x00000FFO > /proc/net/ieee80211/debug_level
2005-07-31 17:05:43 +00:00
For a list of values you can assign to debug_level, you
can look at the bit mask values in <net/ieee80211.h>

If you are not trying to debug or develop the ieee80211
subsystem, you most likely want to say N here.

Include software based cipher suites in support of IEEE
802.11's WEP. This is needed for WEP as well as 802.1x.
This can be compiled as a modules and it will be called
"ieee80211_crypt_wep".

[PATCH] fix IEEE80211_CRYPT_* selects Some of the options didn't obey the most important rule of select If you select something, you have to ensure that the dependencies of what you do select are fulfilled. resulting in the following compile error: <-- snip --> ...
