1962 * When dot11RegulatoryClassesRequired is true and the
1963 * first_channel/reg_extension_id is >= 201 then the IE
1964 * compromises of the 'ext' struct represented below:
1965 *
1966 * - Regulatory extension ID - when generating IE this just needs
1967 * to be monotonically increasing for each triplet passed in
1968 * the IE
1969 * - Regulatory class - index into set of rules
1970 * - Coverage class - index into air propagation time (Table 7-27),
1971 * in microseconds, you can compute the air propagation time from
1972 * the index by multiplying by 3, so index 10 yields a propagation
1973 * of 10 us. Valid values are 0-31, values 32-255 are not defined
1974 * yet. A value of 0 inicates air propagation of <= 1 us.
1975 *
1976 * See also Table I.2 for Emission limit sets and table
1977 * I.3 for Behavior limit sets. Table J.1 indicates how to map
1978 * a reg_class to an emission limit set and behavior limit set.
