Allow GO operation on a channel marked with IEEE80211_CHAN_GO_CONCURRENT iff there is an active station interface that is associated to an AP operating on the same channel in the 2 GHz band or the same UNII band (in the 5 GHz band). This relaxation is not allowed if the channel is marked with IEEE80211_CHAN_RADAR. Note that this is a permissive approach to the FCC definitions, that require a clear assessment that the device operating the AP is an authorized master, i.e., with radar detection and DFS capabilities. It is assumed that such restrictions are enforced by user space. Furthermore, it is assumed, that if the conditions that allowed for the operation of the GO on such a channel change, i.e., the station interface disconnected from the AP, it is the responsibility of user space to evacuate the GO from the channel.

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.

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.

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 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.

---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 that 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.

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.

This option generates an internal data structure representing

the wireless regulatory rules described in net/wireless/db.txt
