First run...
Worst senario 1 dst/pkt w. 64 byte pkts. 2*10 Million packets injected.
eth0, eth2. Input rate 2*190 kpps clone_skb=1. Routing table of 123946
routes. UP. NAPI gives fairmess between both DoS attackers. :-) But more
testing to be done.
plain w. DaveM patch
----------------------------------
72 114 kpps throughput
30271883 12246290 hash misses (second last in my rt_cache_stat)
58% better... and it can be further improved.
