OK, but I have one concern about it.

I'll have to add the attrtype for it anyway. And when later we'll add
yet another one, say INET_DIAG_FOO, we will not be able to request
this in such

   req->ext |= (1 << (INET_DIAG_FOO - 1));

manner as it's currently done. If that's OK, I will rework the patch.

Thanks,
Pavel
