From abb374fe84606ba48cf6c31c14460dfbfb4959e0 Mon Sep 17 00:00:00 2001 From: Ignacio Nunez Hernanz Date: Mon, 26 Feb 2018 12:16:46 +0200 Subject: [PATCH] ath10k: make ath10k report discarded packets to mac80211 Whenever ath10k firmware discards a packet (HTT_TX_COMPL_STATE_DISCARD flag), the skb is freed and mac80211 does not get feedback through ieee80211_tx_status(). Instead, make sure that the IEEE80211_TX_STAT_ACK flag is disabled and let the packet go through, like ath9k does.
