Hi, Thomas

Managed to get the secured mesh up after applying the linked patch. I have
managed to test the HT20 mode for secured mesh and non-secured mesh due to
my embedded platform only supports Fast Ethernet. Here are the results:

Non Secured Mesh (HT20)
# iperf -s -i 1
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[ ID] Interval       Transfer     Bandwidth
[SUM]  0.0-10.0 sec  72.0 MBytes  60.1 Mbits/sec

Secured Mesh (HT20)
# iperf -s -i 1
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[ ID] Interval       Transfer     Bandwidth
[SUM]  0.0-10.1 sec  15.6 MBytes  13.0 Mbits/sec

A bit disappointed that the throughput is drop quite significantly. Confirm
that the aggregation is working:

Rx A-MPDU request on tid 0 result 0
Open BA session requested for 0a:0b:6b:7d:e3:b9 tid 0
activated addBA response timer on tid 0
switched off addBA timer for tid 0
Aggregation is on for tid 0

Chun-Yeow
