From 0c5b93290b2f3c7a376567c03ae8d385b0e99851 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sun, 29 Sep 2013 21:39:34 +0200 Subject: [PATCH] mac80211: update sta->last_rx on acked tx frames When clients are idle for too long, hostapd sends nullfunc frames for probing. When those are acked by the client, the idle time needs to be updated. To make this work (and to avoid unnecessary probing), update sta->last_rx whenever an ACK was received for a tx packet. Only do this if the flag IEEE80211_HW_REPORTS_TX_ACK_STATUS is set.
