SMSC8720A failed to initialise Error in TCP/IP stack
I am getting DRV PHY Init failed (-1 or -3).
When I put probe on the chip it display activity only on REF_LCK and EMDC . All other pins are IDLE.
Both LED are on all the time with green led flashing and Orange LED steady.

It clearly shows that mac is not receiving anything from PHY.
Does anybody have any idea why ?
IS this device failed or some thing related to firmware?
