From 39e68712d75700ec09770c7ad9e8e4abc65db7c6 Mon Sep 17 00:00:00 2001 From: Helmut Schaa Date: Fri, 5 Aug 2011 11:46:19 +0200 Subject: [PATCH] mac80211: Don't use a buf_size=0 in ADDBA requests According to 802.11-2007, 7.3.1.14 it is compliant to use a buf_size of 0 in ADDBA requests. But some devices (AVM Fritz Stick N) arn't able to handle that correctly and will reply with an ADDBA reponse with a buf_size of 0 which in turn will disallow BA sessions for these devices. To work around this problem, initialize hw.max_tx_aggregation_subframes to the maximum AMPDU buffer size 0x40. Using 0 as default for the bufsize was introduced in commit 5dd36bc933e8be84f8369ac64505a2938f9ce036 (mac80211: allow advertising correct maximum aggregate size).
