---help---

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.

config CFG80211_DEVELOPER_WARNINGS

bool "enable developer warnings"

default n
|
help
|
This option enables some additional warnings that help
|
cfg80211 developers and driver developers, but beware that
|
they can also 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).

---help---
|
You should disable this option unless you are both capable
|
and willing to ensure your system will remain regulatory
|
compliant with the features available under this option.
|
Some options may still be under heavy development and
|
for whatever reason regulatory compliance has not or
|
cannot yet be verified. Regulatory verification may at
|
times only be possible until you have the final system
|
in place.
|
|
This option should only be enabled by system integrators
|
or distributions that have done work necessary to ensure
|
regulatory certification on the system with the enabled
|
features. Alternatively you can enable this option if
|
you are a wireless researcher and are working in a controlled
|
and approved environment by your local regulatory agency.

config CFG80211_REG_CELLULAR_HINTS
|
bool "cfg80211 regulatory support for cellular base station hints"
|
depends on CFG80211_CERTIFICATION_ONUS
|
---help---
|
This option enables support for parsing regulatory hints
|
from cellular base stations. If enabled and at least one driver
|
claims support for parsing cellular base station hints the
|
regulatory core will allow and parse these regulatory hints.
|
The regulatory core will only apply these regulatory hints on
|
drivers that support this feature. You should only enable this
|
feature if you have tested and validated this feature on your
|
systems.
|
|
config CFG80211_REG_RELAX_NO_IR
|
bool "cfg80211 support for NO_IR relaxation"
|
depends on CFG80211_CERTIFICATION_ONUS
|
---help---
|
This option enables support for relaxation of the NO_IR flag for
|
situations that certain regulatory bodies have provided clarifications
|
on how relaxation can occur. This feature has an inherent dependency on
|
userspace features which must have been properly tested and as such is
|
not enabled by default.
|
|
A relaxation feature example is allowing the operation of a P2P group
|
owner (GO) on channels marked with NO_IR if there is an additional BSS
|
interface which associated to an AP which userspace assumes or confirms
|
to be an authorized master, i.e., with radar detection support and DFS
|
capabilities. However, note that in order to not create daisy chain
|
scenarios, this relaxation is not allowed in cases where the BSS client
|
is associated to P2P GO and in addition the P2P GO instantiated on
|
a channel due to this relaxation should not allow connection from
|
non P2P clients.
|
|
The regulatory core will apply these relaxations only for drivers that
|
support this feature by declaring the appropriate channel flags and
|
capabilities in their registration flow.

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.

config CFG80211_INTERNAL_REGDB

bool "use statically compiled regulatory rules database" if EXPERT

|
depends on CFG80211
|
---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.
|
|
Using this option requires some parsing of the db.txt at build time,
|
the parser will be upkept with the latest wireless-regdb updates but
|
older wireless-regdb formats will be ignored. The parser may later
|
be replaced to avoid issues with conflicts on versions of
|
wireless-regdb.
|
|
For details see:

Most distributions have a CRDA package. So if unsure, say N.
