Hi, I 'm trying to invoke ATM device operations functions to test MPC8260 SAR driver. The board doesn't consist of Pyhsical layer regarding hardware(like IDT77106) or software(driver). Loopback is done on UTOPIA interface.UTOPIA signals are connected PCI bus.Can anyone please help me out,HOW TO use the following finctions in aplication const struct atmdev_ops mpc8260sar_ops = { open:mpc8260sar_open, close:mpc8260sar_close, ioctl:mpc8260sar_ioctl, getsockopt:mpc8260sar_getsockopt, setsockopt:mpc8260sar_setsockopt, send:mpc8260sar_send, sg_send:mpc8260sar_sg_send, phy_put:mpc8260sar_phy_put, phy_get:mpc8260sar_phy_get, change_qos:mpc8260sar_change_qos, proc_read:mpc8260sar_proc_read, owner:THIS_MODULE, }; I'm new to LINUX ENVIORNMENT with regargs MADHU ________________________________________________________________________ Yahoo!
