From 0edab4ff84b67fc585bb47aba37833da18f5a9dc Mon Sep 17 00:00:00 2001 From: Philipp Borgers <borgers@mi.fu-berlin.de> Date: Mon, 17 May 2021 14:01:45 +0200 Subject: [PATCH] mac80211: minstrel_ht: ignore frame that was sent with noAck flag QoS Data Frames that were sent with a No Ack policy should be ignored by the minstrel statistics. There will never be an Ack for these frames so there is no way to draw conclusions about the success of the transmission.
