Dear Ganesh Reddy
I am pleased to receive your reply
I checked cat /proc/net/dev_mcast in soekris and it has two multicast MAC
addresses in eth1. I think it has been successful in register join group
224.0.0.5 and after that is 224.0.0.6 with kernel
13 eth3 1 0 01005e000001
12 eth2 1 0 01005e000001
11 eth1 1 0 01005e000001
11 eth1 1 0 333300000002
11 eth1 1 0 333300000001
11 eth1 1 0 01005e000005
11 eth1 1 0 01005e000006
10 eth0 1 0 333300000001
10 eth0 1 0 01005e000001
10 eth0 1 0 3333ffc8e27c
