I made several changes in ethernetif.c 

 

pbuf_ref(p);
if (HAL_ETH_Transmit_IT(&heth, &TxConfig) == HAL_OK) {
	while(osSemaphoreAcquire(TxPktSemaphore, TIME_WAITING_FOR_INPUT)!=osOK)
	{
	}
	HAL_ETH_ReleaseTxPacket(&heth);
} else {
	pbuf_free(p);
}
//////////////////////////////////////
/* create a binary semaphore used for informing ethernetif of frame reception */
 RxPktSemaphore = osSemaphoreNew(1, 0, NULL);

 /* create a binary semaphore used for informing ethernetif of frame transmission */
 TxPktSemaphore = osSemaphoreNew(1, 0, NULL);
