 This problem can be reproduced with ease using three nodes(Node 0 -
 x.x.x.7,Node 1 - x.x.x.8 and Node 2 - x.x.x.9) at MSI-Santa Clara.

 Steps to reproduce it on the OLPC testbed at MSI.
 {{{
 1) Reboot the OLPC nodes 7,8,9

 2) Follow these steps:

 At Node 7:

 -bash-3.1# iwpriv msh0 bt_reset

 -bash-3.1# iwpriv msh0 bt_set_invert 1

 -bash-3.1# iwpriv msh0 bt_add 00:17:C4:01:19:9A (MAC of Node 8)
 msh0      bt_add:00:17:C4:01:19:9A

 -bash-3.1# arp -a
 ? (192.168.3.199) at 00:18:E7:15:F4:A8 [ether] on eth0

 -bash-3.1# ping 10.2.51.171 (IP of Node 9) - this ping should ideally fail
