It might be a good idea to consider strategic prefetch points for it.

Vlan code uses several of the methods, so I'm not sure how it will save
any memory
Feeling particularly dense today?
Ahh, yes indeed.

I want to take all the function pointers of 'struct net_device' and
move them to 'struct net_device_ops'. This will save memory for the
case of lots of devices, as well as reduce initialization code.
It will also add an additional deref to every operation, right?

Only one copy of the ops will be needed for all vlan devices:
static const struct netdev_ops vlan_

1. Introduce inline accessors so protocols don't dereference dev->XXX directly.
2. Fix
