81 If drivers determine they need a specific regulatory domain

83 They have two options -- they either provide an alpha2 so that
84 crda can provide back a regulatory domain for that country or
85 they can build their own regulatory domain based on internal
86 custom knowledge so the wireless core can respect it.

110 domain value to a specific alpha2 as follows::
130 			if (regdomain == reg_map->reg) {
131 			alpha2[0] = reg_map->alpha2[0];
132 			alpha2[1] = reg_map->alpha2[1];
139 Lastly, you can then hint to the core of your discovered alpha2, if a match
