commit ecbb416939da77c0d107409976499724baddce7b

[NET]: Fix neighbour destructor handling.
->neigh_destructor() is killed (not used), replaced with
->neigh_cleanup(), which is called when neighbor entry goes to dead
state. At this point everything is still valid: neigh->dev,
neigh->parms etc.
The device should guarantee that dead neighbor entries (neigh->dead !=
0) do not get private part initialized, otherwise nobody will cleanup
it.
I think this is enough for ipoib which is the only user of this thing.
Initialization private part of neighbor entries happens in ipib
start_xmit routine, which is not reached when device is down. But it
would be better to add explicit test for neigh->dead in any case.

Network: convert network devices to use struct device instead of
class_device
This lets the network core have the ability to handle suspend/resume
issues, if it wants to.
Thanks to Frederik Deweerdt <[EMAIL PROTECTED]> for the arm
driver fixes.
