The Linux kernel however does not seem capable of considering them most restrictive subset of multiple rules. Since 5725 ~ 5730 MHz belongs to the next range which has looser requirements, we can do this manually and extend the range by 5 MHz to make the kernel happy and be able to use channel 144. Also, looking at the US regulations, which the TW ones are based on, The DFS range ends at 5730 MHz, while the next range starts at 5735 MHz. This doesn't match the actual regulations, but is skewed to meet wireless channel boundaries. I prefer the database match the law, and be adjuested only if necessary. Signed-off-by: Chen-Yu Tsai --- I have a vague impression that you asked about the range boundaries when I first updated the rules for Taiwan.
