| cfg80211 is the Linux wireless LAN (802.11) configuration API. |

| 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. |

| config CFG80211_DEVELOPER_WARNINGS |

| 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). |

| config CFG80211_CERTIFICATION_ONUS |
| bool "cfg80211 certification onus" |

| default n |
| ---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" |

| ---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. |

| ---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. |
