Both wpa_supplicant and mac80211 have and inactivity timer. By default wpa_supplicant will be timed out in 5 minutes and mac80211's it is 30 minutes. If wpa_supplicant uses a longer timer than mac80211, it will get unexpected disconnection by mac80211. Using 0xffffffff instead as the configured value could solve this w/o changing the code, but due to integer overflow in the expression used this doesn't work. The expression is: (current jiffies) > (frame Rx jiffies + NL80211_MESHCONF_PLINK_TIMEOUT * 250) On 32bit system, the right side would overflow and be a very small value if NL80211_MESHCONF_PLINK_TIMEOUT is sufficiently large, causing unexpectedly early disconnections. Instead allow disabling the inactivity timer to avoid this situation, by passing the (previously invalid and useless) value 0.
