/*
* This regulatory domain control implementation is known to be incomplete
* and confusing. mac80211 regulatory domain control will be significantly
* reworked in the not-too-distant future.
*
* For now, drivers wishing to control which channels are and aren't available
* are advised as follows:
* - set the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag
* - continue to include *ALL* possible channels in the modes registered
* through ieee80211_register_hwmode()
* - for each allowable ieee80211_channel structure registered in the above
* call, set the flag member to some meaningful value such as
* IEEE80211_CHAN_W_SCAN | IEEE80211_CHAN_W_ACTIVE_SCAN |
* IEEE80211_CHAN_W_IBSS.
* - leave flag as 0 for non-allowable channels
*
* The usual implementation is for a driver to read a device EEPROM to
* determine which regulatory domain it should be operating under, then
* looking up the allowable channels in a driver-local table, then performing
* the above.
