Other Parts Discussed in Thread: DP83816


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.
