Actually, looking over the code I see obvious bugs in the logic:
An invalid ethernet address should not cause device loading to fail,
because the user is given the opportunity to supply a MAC address via
userspace (ifconfig or whatever) before the interface goes up.
I just created the attached -bug fix- patch as illustration, though I
have not committed it, waiting for comment.
This patch will make no difference for users hitting invalid-eep-csum
rather than invalid-MAC-addr condition, but it's a problem I noticed
while reviewing Adam's patch in detail.
Adding my own comment :)
Does the ethernet stack check is_valid_ether_addr() before permitting
interface-up?
I'm wondering if there is a way to avoid adding
if (!is_valid_ether_addr(dev->dev_addr))
return -EINVAL;
to every ethernet driver's ->open() hook.
