In the private data structure of LAN driver ( in the
"devs_eth_sh_sn7760.inl" file) I do not set the interrupt item. I only set
base address as following:

static lan91cxx_priv_data lan91cxx_eth0_priv_data = {

   config_enaddr : sn7760_get_ESA,
#ifndef CYGSEM_DEVS_ETH_SH_SN7760_REDBOOT_ESA
   enaddr: CYGDAT_DEVS_ETH_SH_SN7760_ESA,
#endif
#if 0
   base : (unsigned short *) SA1110_FHH_ETH_IOBASE,
   attbase : (unsigned char *) SA1110_FHH_ETH_MMBASE,
   interrupt : SA1110_IRQ_GPIO_ETH
#else
   base : (unsigned short *) 0x94000000,
#endif
};

It is as the same as the "innovator" platform did. Another reason is I don't
know how to set this item.

Thank you and looking forward to further advice.
