Comment:

 I have done further testing and I believe joyride cannot receive multicast
 frames.

 I am using this app to test:
 http://www.venaas.no/multicast/ssmping/

 I put 2 708 systems on the same mesh channel. One runs ssmpingd, another
 runs ssmping, and the ssmping box receives both unicast and multicast
 responses as expected.

 Swap one of the 708 systems for joyride, and repeat the test. Joyride
 running ssmpingd, 708 running ssmping: 708 receives both unicast and mcast
 responses - good.

 Swap the arrangement so that 708 runs ssmpingd and joyride runs ssmping:
 joyride only receives unicast responses.

 Running libertas firmware 5.110.22p14 on all the systems. This is the
 version shipped in joyride and in 708.
