DP83848Q-Q1: ARP Retry count exceeded; starting again

Hi,

I am getting the below Error,

"ARP Retry count exceeded; starting again" in Uboot

I had configured the PHY control register 00H as 0x1000 (Only Auto-Negotiation Enabled) under this condition  ping is not working in uboot. and I had also configured PHY control register 00H as 0x5000(loopback and Auto-Negotiation Enabled) Under hardware loop back also i am getting the same error.

Please find the log below and do advice how to resolve
