Hi Aurelien,

There were some of my comments you haven't addressed yet, comments in-line.

ipv6_addr_set(&addr6, 0, 0, htonl(0x0000FFFF), ncp->cl_addrlist[i]);

ipv6_addr_set(&in6, 0, 0, htonl(0x0000FFFF), sin->sin_addr);

ipv6_addr_set(&in6, 0, 0, htonl(0x0000FFFF), sin->sin_addr);

This is unused, can go away.

If you use ipv6_addr_set() everywhere you don't need this.

Guessing you changed a tab to a space, unnecessary.

I still think you should pass a pointer here.

And here.

And here.
