| 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: |

| https://wireless.wiki.kernel.org/en/developers/Documentation/cfg80211 |
| |
| When built as a module it will be called cfg80211. |

| 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). |

| 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. |

| 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 |

| 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. |
