To illustrate this, let's take the first driver touched by 4/x.
In 3c503, the function init_module() essentially does
for each ioaddr
if (do_el2_probe(ioaddr) == 0)
return 0
And do_el2_probe() just calls el2_probe1() which is similar
to your average PCI probe function except that the first thing
it does is to make sure that the device exists at ioaddr.
This is not that different from PCI where it would look
like
for each PCI device matching the vendor/product numbers
if (do_el2_probe(device) == 0)
return 0
Now before my patch, register_netdev was being called just
after do_el2_probe() returns. My patch simply moves it to
the end of el2_probe1() which is exactly what would happen
if this were a PCI driver.
I've rediffed it against today's BK tree.
Cheers,
