9What: old static regulatory information and ieee80211_regdom module parameter 9What: The ieee80211_regdom module parameter
10When: 2.6.29 10When: March 2010 / desktop catchup
11
12Why: This was inherited by the CONFIG_WIRELESS_OLD_REGULATORY code,
13 and currently serves as an option for users to define an
14 ISO / IEC 3166 alpha2 code for the country they are currently
15 present in. Although there are userspace API replacements for this
16 through nl80211 distributions haven't yet caught up with implementing
17 decent alternatives through standard GUIs. Although available as an
18 option through iw or wpa_supplicant its just a matter of time before
19 distributions pick up good GUI options for this. The ideal solution
20 would actually consist of intelligent designs which would do this for
21 the user automatically even when travelling through different countries.
22 Until then we leave this module parameter as a compromise.
23
24 When userspace improves with reasonable widely-available alternatives for
25 this we will no longer need this module parameter. This entry hopes that
26 by the super-futuristically looking date of "March 2010" we will have
27 such replacements widely available.
