- bool "Full debugging output for the old IEEE80211 stack"
- depends on IEEE80211
- ---help---
- This option will enable debug tracing output for the
- ieee80211 network stack.
-
- 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
-
- 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.

-In the event that fragmentation is required, the incoming payload is split into
-N parts of size ieee->fts. The first fragment contains the SNAP header and the
-remaining packets are just data.
-
-If encryption is enabled, each fragment payload size is reduced by enough space
-to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
-So if you have 1500 bytes of payload with ieee->fts set to 500 without
-encryption it will take 3 frames. With WEP it will take 4 frames as the
-payload of each frame is reduced to 492 bytes.
