In WRL-5.0.1, ping6 to the T4240 target fails. PING6 fails because the target is ignoring the Neighbor Solicitation message sent from the remote host. ifconfig output shows that Rx packets are not getting incremented.  Also, when seen through the fman statistics of T4240 ./sys/devices/ffe000000.soc/ffe400000.fman/ffe48c000.port/statistics/p
ort_frame is not getting incremented. 

The problem seems to be that the multicast packets are not being accepted by the target.
when the Ethernet interface is set to PROMISCUOUS mode the target is responding to the NS and ping6 works.

Steps to Reproduce

1. "ifconfig eth1 add 2001::1/64 up" in T4240, 

and "ifconfig eth0 add 2001::2/64 up" in remote host

2. ping6 2001::1 from the remote host fails.
