ST32F407 got HAL_ETH_ERROR_DMA when I plugin the ethernet cable - stm32

Question

I have an STM32F407 with the ethernet PHY DP83848.
I cannot ping the device if I'm using the LwIP because I'm facing some errors.
I do the following steps to reproduce the error.
I start up my PCB board
I let the initialization do its job and I get no error back.
I plugin my ethernet cable
I ping a random device with a random number
Then my activity LED blink on the DP83848 and then I get an interrupt.
I get the error code 0x8. That means I'm facing DMA issues. But why?
/** #defgroup ETH_Error_Code ETH Error Code
* #{
*/
#define HAL_ETH_ERROR_NONE ((uint32_t)0x00000000U) /*!< No error */
#define HAL_ETH_ERROR_PARAM ((uint32_t)0x00000001U) /*!< Busy error */
#define HAL_ETH_ERROR_BUSY ((uint32_t)0x00000002U) /*!< Parameter error */
#define HAL_ETH_ERROR_TIMEOUT ((uint32_t)0x00000004U) /*!< Timeout error */
#define HAL_ETH_ERROR_DMA ((uint32_t)0x00000008U) /*!< DMA transfer error */
#define HAL_ETH_ERROR_MAC ((uint32_t)0x00000010U) /*!< MAC transfer error */
#if (USE_HAL_ETH_REGISTER_CALLBACKS == 1)
#define HAL_ETH_ERROR_INVALID_CALLBACK ((uint32_t)0x00000020U) /*!< Invalid Callback error */
#endif /* USE_HAL_ETH_REGISTER_CALLBACKS */
/**
* #}
*/
My STM32F407 does not have DMA for Ethernet. What should I do now? Is this a bug?

Update:
I found a DMA error code.
I get that error from here. See arrow
/* ETH DMA Error */
if (__HAL_ETH_DMA_GET_IT(heth, ETH_DMASR_AIS))
{
if (__HAL_ETH_DMA_GET_IT_SOURCE(heth, ETH_DMAIER_AISE))
{
heth->ErrorCode |= HAL_ETH_ERROR_DMA;
/* if fatal bus error occurred */
if (__HAL_ETH_DMA_GET_IT(heth, ETH_DMASR_FBES))
{
/* Get DMA error code */
heth->DMAErrorCode = READ_BIT(heth->Instance->DMASR, (ETH_DMASR_FBES | ETH_DMASR_TPS | ETH_DMASR_RPS)); <<--- HERE!
/* Disable all interrupts */
__HAL_ETH_DMA_DISABLE_IT(heth, ETH_DMAIER_NISE | ETH_DMAIER_AISE);
/* Set HAL state to ERROR */
heth->gState = HAL_ETH_STATE_ERROR;
}
else
{
/* Get DMA error status */
heth->DMAErrorCode = READ_BIT(heth->Instance->DMASR, (ETH_DMASR_ETS | ETH_DMASR_RWTS |
ETH_DMASR_RBUS | ETH_DMASR_AIS));
/* Clear the interrupt summary flag */
__HAL_ETH_DMA_CLEAR_IT(heth, (ETH_DMASR_ETS | ETH_DMASR_RWTS |
ETH_DMASR_RBUS | ETH_DMASR_AIS));
}
The error message says that DMA is not avaiable for ETH. Is that a bug then?
