We could just request sessions without a timeout in the first place. Or do you have a strong reason to need the timeout, such as limited hardware resources for (TX) aggregation sessions? But then maybe you should just time them out based on FW statistics directly, rather than having to periodically refresh the timer in mac80211? I don't mind the patch, and I'll happily take it if it's needed, I'm just wondering if that isn't a very roundabout way of achieving things. johannes
