Hi

I don't understand this code line:

```nohighlight
struct iphdr *iph=(struct iphdr *)data;

```

where data is an u\_char.  
What I can see is that we are creating a pointer (iph) to a iphdr struct, but the right side is not very clear. Can anyone explain the meaning, please?

Thanks in advance

Dedalus
