Ethernet interupt not interupting

I having problem with the Ethernet interupt. I got the transmit and receive to work but I can't get the interupt to work.

The ethernet is set up by:

Code:

void PF_Enet_Init(void)

{

ENET_InitClocksGPIO(); /* configure all GPIO */

ENET_Init(PHY_FULLDUPLEX_100M); /* Operating mode = Fullduplex 100Mbs */

ENET_Start(); /* start Receive & Transmit */

PF_Setup_INT(ENET_ITLine, PF_Enet_Interrupt); // Sets up interupt

}

and the PF_Setup_INT looks like:

Code:

void PF_Setup_INT(uint16 VIC_Source, void (*InterruptFunction)(void))

{

uint16 Priority;

if(VIC_Source < VIC_REGISTER_NUMBER)

{

Priority = VIC_Source;

VIC0->VAiR[Priority] = (uint32)InterruptFunction; //Configuration of the ISR vector address

VIC0->INTSR &= ~(VIC_MASK << Priority); //Set interrupt type to IRQ

VIC0->VCiR[Priority] |= VIC_VECTOR_ENABLE_MASK; //Enable vector interrupt

VIC0->VCiR[Priority] &= VIC_IT_SOURCE_MASK; //Select the interrupt source

VIC0->VCiR[Priority] |= Priority; //and set the priority

VIC0->INTER |= (VIC_MASK << Priority); //Enable the interrupt request lines.

Vic0Inter = VIC0->INTER;

}

else

{

Priority = VIC_Source - VIC_REGISTER_NUMBER;

VIC1->VAiR[Priority] = (uint32)InterruptFunction; //Configuration of the ISR vector address

VIC1->INTSR &= ~(VIC_MASK << Priority); //Set interrupt type to IRQ

VIC1->VCiR[Priority] |= VIC_VECTOR_ENABLE_MASK; //Enable vector interrupt

VIC1->VCiR[Priority] &= VIC_IT_SOURCE_MASK; //Select the interrupt source

VIC1->VCiR[Priority] |= Priority; //and set the priority

VIC1->INTER |= (VIC_MASK << Priority); //Enable the interrupt request lines.

Vic1Inter = VIC1->INTER;

}

}

I have based my code on STR91x_webserver_v1_1 but this code does not use interupt in ethernet which I require.

Anyone have a suggestion what I've missed?

I've found out what I've missed.

In the init i added:

ENET_DMA->IER = 0x80; // enable interupt when RX done

and in the interupt I've added:

ENET_DMA->ISR = 0x80; // Clear the interupt status for RX done
