Not entirely sure, and I don't think we've even seen a device where this code path runs (it only runs if a certain bit is set in the EEPROM). However, considering that this looks like it plays with some kind of radio stuff, and it's simple to implement, it makes sense to at least meet the behavior of the vendor driver (as opposed to violating some weird regulation somewhere). > I don't know what channel 1 and 11 have in common.

The vendor driver is full of stuff like this, many corners have been cut. Chances are that they just wanted to hit the edges in the common domain while not breaking things for channel 12~14 users, and didn't go the full way of implementing it accurately. I will email the developers for clarification.
