Hi Mugunthan,

I've been playing with the dual_emac mode and I noticed that if eth0 receives broadcasts packets then it will forward them to eth1. I assume that it either has one ALE rule too much or is missing one. Do you have any idea what it might be?

I've also encountered this problem. See this thread:

Still had no time to dig the driver and TRM. Hope Mugunthan can help to sort the things out.
