Iperf measurenment

[Ramon Fontes]

Hi Janusz, take a look at the results (still more than 1Gb/s):

Client:

iperf -V -c fe80::ff:fe00:100%sta1-wlan0 -t 20
------------------------------------------------------------
Client connecting to fe80::ff:fe00:100%sta1-wlan0, TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[ 14] local fe80::ff:fe00:0 port 51271 connected with fe80::ff:fe00:100
port 5001
[ ID] Interval       Transfer     Bandwidth
[ 14]  0.0-20.0 sec  2.88 GBytes  1.24 Gbits/sec
------------------------------------------------------------

Server:

Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[ 15] local fe80::ff:fe00:100 port 5001 connected with fe80::ff:fe00:0 port
51271
[ ID] Interval       Transfer     Bandwidth
[ 15]  0.0-10.0 sec  1.44 GBytes  1.24 Gbits/sec
[ 15] 10.0-20.0 sec  1.44 GBytes  1.23 Gbits/sec
[ 15]  0.0-20.0 sec  2.88 GBytes  1.24 Gbits/sec

Client (sta1-wlan0) and Server (sta2-wlan0) are stations that are connect
to the AP (using hostapd) on the wlan3 interface.
