dev_get_by_name example

[Ran Shalit]

Hello,

How should we use dev_get_by_name ?
What should be the 1st parameter should it be a pointer ? (without
allocation required) ?
struct net_device *dev_get_by_name(struct net *net, const char *name);
I get an exception when using it for unallocated pointer in 1st
argument, but succeeded with the following:
    ndev =  dev_get_by_name(&init_net, "eth0");
Is it alloweed to use init_net ?

Regards,
Ran
