Johannes Berg 04b7b2ff50 mac80211: handle power constraint/country IE better ... Currently, mac80211 uses the power constraint IE, and reduces the regulatory max TX power by it. This can cause issues if the AP is advertising a large power constraint value matching a high TX power in its country IE, for example in this case: ... Country: US Environment: Indoor/Outdoor ... Channels [157 - 157] @ 30 dBm ... Power constraint: 13 dB ... What happened here is that our local regulatory TX power is 15 dBm, and gets reduced by 13 dB so we end up with only 2 dBm effective TX power, which is way too low. Instead, handle the country IE/power constraint IE combined and restrict our TX power to the max of the regulatory power and the maximum power advertised by the AP, in this case 17 dBm (= 30 dBm - 13 dB). Also print a message when this happens to let the user know and help us debug issues with it. Reported-by: Carl A. Cook <CACook@quantum-equities.com> Tested-by: Carl A.
