[B.A.T.M.A.N.] batman-adv bonding feature - unable to get data packets fragmented into multiple wireless interfaces

[syed moulana]

hi

I tested the throughput between point to point mesh nodes using single
and 2 radios.

1.  Using single radio (ch 5180)  the resulting throughput for HT40+
           TCP max 250mbit/s
           UDP - max 320mbit/s

2. Using 2 radios with and without batctl bonding enabled (ch 5180 for
wlan0, ch 5785 for wlan1), the resulting throughput for HT40+ is same.
           with batctl bonding and fragmentation enabled I believed I
should be getting 50% gain in througput.
    When I monitor the wlan0 and wlan1 interfaces using batctl tcpdump
-p 4 wlanx I can see that iperf data are interleaved.
    There is no splitting of data frames into 2 wireless interfaces.

Please advice
