[IPV4] raw: Strengthen check on validity of iph->ihl We currently check that iph->ihl is bounded by the real length and that the real length is greater than the minimum IP header length. However, we did not check the caes where iph->ihl is less than the minimum IP header length. This breaks because some ip_fast_csum implementations assume that which is quite reasonable.
