(usagi-users 03609) IPv6 setsockopt software MTU patch

Hi,

In my precedent mails, i pointed out that IPV6_MTU setsockopt
was ineffective because the field frag_size was not used further
in the ipv6 fragment code of the kernel. You can check out
that this is the case by this simple proof of concept code :

The fix is very simple, it only grab the value of frag_size and
use it in ip6_fragment file, could you please review the patch which
fix that problem at :

Thanks for the attention,
