1) I can't understand relationship between, say, pci driver and network driver.
If my ethernet controler is hosted on a pci bus is this device a struct
net_device or a struct pci_dev ? If it is a pci_dev it's registered by the pci
core before the core calls the probe callback of my driver. If it is a
net_device my driver must call register_netdev for the device. What's the right
way ? (if both device structures are needed when to load the module which holds
net_device driver code with respect to the loading of the module which holds
pci_dev driver code ?)
(I have focused on struct net_device as an example but the same question
happens for other classes of devices whose controler can be hosted on a pci
bus).
2) An other (unrelated) question is : why usb driver must register itself the
devices it is bounded to ? (unlike pci driver). It would make sens to have the
same registration scheme for devices on both buses.
Thanks for help.
