this initializes a few net_device structure variables.
As the name suggests, it shud be used when allocating net_device for an
ethernet interface.

alloc_etherdev() calls alloc_netdev(..., ether_setup)
alloc_netdev calls ether_setup() to setup the net_device members to
ethernet functions/values.

So, both methods are almost equivalent.

Check out the sources...use lxr.linux.no
