we are using DP83816 in our design for dual redundant Ethernet module. 
we are facing some issues. 
1. At 100mbps configured the two Ethernet ports. Without any connection the
channel B is connected and packets are incrementing Intially. 
2. At different speeds channel A at 10 MBPS and Channel B at 100 MBPS. Channel
A is up without any connection.
