标题: RMII 驱动读写问题请教
之前是用的MII的，下面驱动可以正常工作，但换成RMII后，下面ioctl操作报错，请问要怎么修改：
static int network_miireg_read(char *ifrname, int phy_id, int reg_num )
{
while(ret==0){
      fd = socket(AF_INET, SOCK_DGRAM, 0);

      if(-1 == fd)
      {
            porting_error(PORT_MODULE_NET,"get socket fail.");
            return 0;
      }

      ifr = malloc(sizeof(struct ifreq));
      memset(ifr, 0x00, sizeof(struct ifreq));
      //strcpy (ifr->ifr_name, ifrname);       /*eth0*/
      strncpy(ifr->ifr_name, ifrname, IFNAMSIZ);
      mii = (struct mii_ioctl_data *)&ifr->ifr_data;
      mii->phy_id =0; // phy_id;       /*0x10;*/
      //phy_id = mii->phy_id;
      mii->reg_num = reg_num;       /*0x01;*/

      /*mii->val_in = SetValue;*/
      if(ioctl(fd, ActionCmd, ifr) == -1)
      {
            close(fd);
            porting_error(PORT_MODULE_NET,"ioctl fail.");
            free(ifr);
            return 0;
      }
      close(fd);
      // printf("read value = 0x%x\n", mii->val_out);
      ret = mii->val_out;
      free(ifr);
      count++;
      if(count > 3)
               break;
      if(ret==0)
               sleep(1);
      }
}
