28 | cfg80211 is the Linux wireless LAN (802.11) configuration API. | |
29 | Enable this if you have a wireless device. | |
30 | ||
31 | For more information refer to documentation on the wireless wiki: | |
32 | ||
33 | http://wireless.kernel.org/en/developers/Documentation/cfg80211 | |
34 | ||
35 | When built as a module it will be called cfg80211. | |

37 | config NL80211_TESTMODE |
38 | bool "nl80211 testmode command" | |
39 | depends on CFG80211 | |
40 | help | |
41 | The nl80211 testmode command helps implementing things like | |
42 | factory calibration or validation tools for wireless chips. | |
43 | ||
44 | Select this option ONLY for kernels that are specifically | |
45 | built for such purposes. | |
46 | ||
47 | Debugging tools that are supposed to end up in the hands of | |
48 | users should better be implemented with debugfs. | |

53 | bool "enable developer warnings" | |
54 | depends on CFG80211 | |
55 | default n | |
56 | help | |
57 | This option enables some additional warnings that help | |
573a2b51 OO |
58 | cfg80211 developers and driver developers, but beware that |
59 | they can also trigger due to races with userspace. | |
f7969969 JB |
60 | |
61 | For example, when a driver reports that it was disconnected | |
62 | from the AP, but the user disconnects manually at the same | |
63 | time, the warning might trigger spuriously due to races. | |
64 | ||
65 | Say Y only if you are developing cfg80211 or a driver based | |
66 | on it (or mac80211). | |

73 | ---help--- | |
74 | You should disable this option unless you are both capable | |
75 | and willing to ensure your system will remain regulatory | |
76 | compliant with the features available under this option. | |
77 | Some options may still be under heavy development and | |
78 | for whatever reason regulatory compliance has not or | |
79 | cannot yet be verified. Regulatory verification may at | |
80 | times only be possible until you have the final system | |
81 | in place. | |
82 | ||
83 | This option should only be enabled by system integrators | |
84 | or distributions that have done work necessary to ensure | |
85 | regulatory certification on the system with the enabled | |
86 | features. Alternatively you can enable this option if | |
87 | you are a wireless researcher and are working in a controlled | |
88 | and approved environment by your local regulatory agency. | |

120 | Note that you need to also select the correct CRYPTO_<hash> modules |
121 | for your certificates, and if cfg80211 is built-in they also must be. | |

125 | depends on CFG80211_CERTIFICATION_ONUS | |
126 | ---help--- | |
127 | This option enables support for parsing regulatory hints | |
128 | from cellular base stations. If enabled and at least one driver | |
129 | claims support for parsing cellular base station hints the | |
130 | regulatory core will allow and parse these regulatory hints. | |
131 | The regulatory core will only apply these regulatory hints on | |
132 | drivers that support this feature. You should only enable this | |
133 | feature if you have tested and validated this feature on your | |
134 | systems. | |

137 | bool "cfg80211 support for NO_IR relaxation" | |
138 | depends on CFG80211_CERTIFICATION_ONUS | |
139 | ---help--- | |
140 | This option enables support for relaxation of the NO_IR flag for | |
141 | situations that certain regulatory bodies have provided clarifications | |
142 | on how relaxation can occur. This feature has an inherent dependency on | |
143 | userspace features which must have been properly tested and as such is | |
144 | not enabled by default. | |
145 | ||
146 | A relaxation feature example is allowing the operation of a P2P group | |
147 | owner (GO) on channels marked with NO_IR if there is an additional BSS | |
148 | interface which associated to an AP which userspace assumes or confirms | |
149 | to be an authorized master, i.e., with radar detection support and DFS | |
150 | capabilities. However, note that in order to not create daisy chain | |
573a2b51 | 151 | scenarios, this relaxation is not allowed in cases where the BSS client |
174e0cd2 IP |
152 | is associated to P2P GO and in addition the P2P GO instantiated on |
153 | a channel due to this relaxation should not allow connection from | |
154 | non P2P clients. | |
155 | ||
156 | The regulatory core will apply these relaxations only for drivers that | |
157 | support this feature by declaring the appropriate channel flags and | |
158 | capabilities in their registration flow. | |
