1477 | * When dot11RegulatoryClassesRequired is true and the | |
1478 | * first_channel/reg_extension_id is >= 201 then the IE | |
1479 | * compromises of the 'ext' struct represented below: | |
1480 | * | |
1481 | * - Regulatory extension ID - when generating IE this just needs | |
1482 | * to be monotonically increasing for each triplet passed in | |
1483 | * the IE | |
1484 | * - Regulatory class - index into set of rules | |
1485 | * - Coverage class - index into air propagation time (Table 7-27), | |
1486 | * in microseconds, you can compute the air propagation time from | |
1487 | * the index by multiplying by 3, so index 10 yields a propagation | |
1488 | * of 10 us. Valid values are 0-31, values 32-255 are not defined | |
1489 | * yet. A value of 0 inicates air propagation of <= 1 us. | |
1490 | * | |
1491 | * See also Table I.2 for Emission limit sets and table | |
1492 | * I.3 for Behavior limit sets. Table J.1 indicates how to map | |
1493 | * a reg_class to an emission limit set and behavior limit set. | |
