pf: Limit the maximum number of fragments per packet Similar to the network stack issue fixed in r337782 pf did not limit the number of fragments per packet, which could be exploited to generate high CPU loads with a crafted series of packets. Limit each packet to no more than 64 fragments. This should be sufficient on typical networks to allow maximum-sized IP frames. This addresses the issue for both IPv4 and IPv6.
