From 0f2a2c5d4962a315c1c6be875d91a756d3c8df7e Mon Sep 17 00:00:00 2001 From: Sara Sharon Date: Fri, 20 Apr 2018 13:49:19 +0300 Subject: [PATCH] mac80211: use timeout from the AddBA response instead of the request [ Upstream commit 914eac248d876f9c00cd1792ffec3d182c863f13 ] 2016 spec, section 10.24.2 specifies that the block ack timeout in the ADD BA request is advisory. That means we should check the value in the response and act upon it (same as buffer size).
