The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

cfg80211 is the Linux wireless LAN (802.11) configuration API.
|
|
Enable this if you have a wireless device.
|
|
|
|
For more information refer to documentation on the wireless wiki:
|
|
|
|
http://wireless.kernel.org/en/developers/Documentation/cfg80211
|
|
|
|
When built as a module it will be called cfg80211.

help
|
|
The nl80211 testmode command helps implementing things like
|
|
factory calibration or validation tools for wireless chips.
|
|
|
|
Select this option ONLY for kernels that are specifically
|
|
built for such purposes.
|
|
|
|
Debugging tools that are supposed to end up in the hands of
|
|
users should better be implemented with debugfs.
|
|

Say N.

default n
|
|
help
|
|
This option enables some additional warnings that help
|
|
cfg80211 developers and driver developers, but that can
|
|
trigger due to races with userspace.
|
|
|
|
For example, when a driver reports that it was disconnected
|
|
from the AP, but the user disconnects manually at the same
|
|
time, the warning might trigger spuriously due to races.
|
|
|
|
Say Y only if you are developing cfg80211 or a driver based
|
|
on it (or mac80211).

You can enable this if you want to debug regulatory changes.
|

|
|
wiki:

This option enables powersave mode by default.
|
|
|
|
If this causes your applications to misbehave you should fix your
|
|
applications instead -- they need to register their network
|
|
latency requirement, see Documentation/power/pm_qos_interface.txt.

---help---
|
|
This option generates an internal data structure representing
|
|
the wireless regulatory rules described in net/wireless/db.txt
|
|
and includes code to query that database. This is an alternative
|
|
to using CRDA for defining regulatory rules for the kernel.
|
|
|
|
For details see:
|
|
|
|
http://wireless.kernel.org/en/developers/Regulatory
|
|
|
|
Most distributions have a CRDA package. So if unsure, say N.
