Hello,

I don't know if this is the right place where to ask, but I was 
wondering why the dev_loopback_xmit function defined in /net/core/dev.c 
takes struct net * and struct sock *  as parameters. They are never 
used, so I believe passing only the struct  sk_buff * should be enough.

In addition, it would like to know where I can read what is and how to 
set a skb dst_entry, since I don't really understand it.

Thanks a lot,

Emanuele
