First, i am not using the circuit i sketched above, i have only a Cap 100nF on the transformer PIN 4 (in the middle of the transformer) with out this the Tx+ and Tx- after the magnetics are equal.

Second, I am using the exact code of the fpga4fun.com which is tested from many users, so its not a fpga problem, its on the transmittion and probably i have done some mistake on my pcb and the ethernet packets can be received from the PC.

If you can help me further it will be appreciated.
