Comment(by jcardona):

 This works for me.  To test:

 In one xo, associate to AP, then:

 {{{
 # arp -s 192.168.1.33 33:33:00:00:00:00
 }}}

 Put a second xo in monitor mode to capture traffic:
 {{{
 # echo 0x1 > /sys/class/net/msh0/device/libertas_rtap
 # ifconfig rtap0 up
 # tcpdump -i msh0 -l host 192.168.1.33
 22:27:24.304679 1.0 Mb/s 0 MHz antenna 0 114dB signal [0x0000000e]
 DA:33:33:00:00:00:00 (oui Unknown) BSSID:00:13:10:fc:57:ff (oui Unknown)
 SA:00:17:c4:05:2a:c7 (oui Unknown) LLC, dsap SNAP (0xaa) Individual, ssap
 SNAP (0xaa) Command, ctrl 0x03: oui Ethernet (0x000000), ethertype IPv4
 (0x0800): 192.168.1.200 > 192.168.1.33: ICMP echo request, id 19463, seq
 331, length 64
 }}}

 I don't have an out-of-the-box build, though:

 {{{
 # cat /boot/olpc_build
 645
 # ethtool -i msh0
 driver: libertas
 version: COMM-USB8388-322.p1-dbg
 firmware-version: 5.110.20.p47
 bus-info:
 }}}
