ETHERNET C6748 is not able to receive

Hello,

I am using custom board similar to the LCDKC6748 and i am trying Ethernet communications.

I am able to have alive and link to the PHY LAN8710A by checking the mdio and emac register bunch.

I am able to transmit the data by writing the transmission descriptor and able to see the interrupt on channel TXINTSTATRAW.

Now, i placed phy in the loop-back mode to verify the receive channel.

I am seeing nothing in RXINTSTATRAW and even on RXGOODFRAMES registers.

Any clues?
