1241 | * switch here, but that resulted in playing whack a mole. | |
1242 | * More importantly wrongly reporting the wifi radio as hw-blocked, results in | |
1243 | * non working wifi. Whereas not reporting it hw-blocked, when it actually is | |
1244 | * hw-blocked results in an empty SSID list, which is a much more benign | |
1245 | * failure mode. | |
1246 | * So the default now is the much safer option of assuming there is no | |
1247 | * hardware rfkill switch. This default also actually matches most hardware, | |
1248 | * since having a hw rfkill switch is quite rare on modern hardware, so this | |
1249 | * also leads to a much shorter list. | |
