16 * are advised as follows:
17 * - set the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag
18 * - continue to include *ALL* possible channels in the modes registered
19 * through ieee80211_register_hwmode()
20 * - for each allowable ieee80211_channel structure registered in the above
21 * call, set the flag member to some meaningful value such as
22 * IEEE80211_CHAN_W_SCAN | IEEE80211_CHAN_W_ACTIVE_SCAN |
23 * IEEE80211_CHAN_W_IBSS.
24 * - leave flag as 0 for non-allowable channels
25 *
26 * The usual implementation is for a driver to read a device EEPROM to
27 * determine which regulatory domain it should be operating under, then
28 * looking up the allowable channels in a driver-local table, then performing
29 * the above.
