how kernel detect device and make proble() called?

[hong zhang]

List,

Example is PCI ethernet card. how kernel knows NIC is inserted to PCI bus and call .probe?

static struct pci_driver e1000_driver = {

	.name     = e1000_driver_name,

	.id_table = e1000_pci_tbl,

	.probe    = e1000_probe,

	.remove   = __devexit_p(e1000_remove),

#ifdef CONFIG_PM

	/* Power Management Hooks */

	.suspend  = e1000_suspend,

	.resume   = e1000_resume,

#endif

#ifndef USE_REBOOT_NOTIFIER

	.shutdown = e1000_shutdown,

#endif

#ifdef HAVE_PCI_ERS

	.err_handler = &e1000_err_handler

#endif

};
