[ECOS] Question about eth_drv_int_vector() in Redboot?

When using ethernet driver in Redboot.
Call stack:
  net_init()
  net_io_init()
  net_io_control( comm, __COMMCTL_IRQ_DISABLE )
  vector = eth_drv_int_vector()
  eth_drv_int_vector(void)
  MYDRIVER_int_vector(struct eth_drv_sc *sc);

Here eth_drv_int_vector() need MYDRIVER_int_vector() to return its 
interrupt vector, but on my target, this ethernet device does not use any 
interrupt resource.

How to return the vector? Presently, I return 0, and it works.
Since 0 is a valid vector used by other driver, I suspect it is not good.

Thanks in advance.

Redboot does not use interrupts, so it is not really a problem at the
moment. 

If you want to use full eCos on your target then it becomes a
problem. eCos assumes the ethernet is interrupt driven so i think you
will then have more problems.
