From 47df8e059b49a80c179fae39256bcd7096810934 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 8 Aug 2020 19:25:42 +0200 Subject: mac80211: reduce packet loss event false positives When running a large number of packets per second with a high data rate and long A-MPDUs, the packet loss threshold can be reached very quickly when the link conditions change. This frequently shows up as spurious disconnects. Mitigate false positives by using a similar logic for regular stations as the one being used for TDLS, though with a more aggressive timeout. Packet loss events are only reported if no ACK was received for a second.
