Hello, Thierry
I recently had the same problems with GRUB netbooting, and already
done just what you suggested:
added new field to pci_device struct - pointer to correct probe
routine:
struct pci_device {
unsigned short vendor, dev_id;
const char *name;
unsigned int membase;
unsigned short ioaddr;
unsigned short devfn;
struct nic *(*eth_probe)(struct nic *, unsigned short *,
struct pci_device *);
};
and added code to call the correct probe function before trying
all the drivers. I was in doubt whom I shoud bug with it: Okuji or
Etherboot maintainers. I attached my patch to this message so
we avoid unneeded duplication of efforts. This is my current and
working version.
By the way I looked into recent Etherboot distribution
and found that version in grub is quite dated 5 or 8 month old,
Etherboot has some new drivers, pci_device struct is also changed.
However this problem with non-optimal probing sequence of pci devices
still exists in Etherboot too.
Regards,
Eugene
