Setup:
- Intel network card
- e1000e standard linux driver in autorun
- myModule; customized e1000e driver by me for debugging reasons

Steps:
- after power on execute 'rmmod e1000e'
- 'insmod myModule'
From my debuging experience I see, that .probe function is fired always after 'insmod myModule' (when e1000e is not present).

Steps
- after power on do not remove 'e1000e' driver
- 'insmod myModule'
Now .probe function from myModule is not executed. Only init_module function operates.

What if I add myModule to autorun? Will .probe function be then executed? I don't know. I have no idea how to add myModule to autorun. Smilie

I guess .probe is 'must be', because there are important lines like:

Code:

.probe function:
{
 netdev = alloc_etherdev
 SET_MODULE_OWNER(netdev);
  netdev->netdev_ops        = &e1000e_netdev_ops;
 err = register_netdev(netdev);
}

static const struct net_device_ops e1000e_netdev_ops = {
    .ndo_open        = e1000_open,    // e.g. ifconfig up
    .ndo_stop        = e1000_close,    // e.g. ifconfig down
    .ndo_start_xmit        = e1000_xmit_frame,
    .ndo_get_stats        = e1000_get_stats,
    .ndo_tx_timeout        = e1000_tx_timeout,
    .ndo_validate_addr    = eth_validate_addr,
};
