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 5dd36bc9 (mac80211: allow advertising correct maximum aggregate size). Signed-off-by:Helmut Schaa <helmut.schaa@googlemail.com> Acked-by:
