Yes
Excellent work.

I make some real life tests with 10Gbit traffic and make some rdos.
With kernel 3.4.5 when I reach 6M routing cache entries - traffic is not 
forwarded - on my hardware with 64G RAM

With kernel - 3.5.0-rc7-next-20120720 + David M. patches - route cache 
removal + fix
Traffic is forwarder all the time at speed 8.2Mpps RX from traffic 
generator and 8.2Mpps TX to the sink

Also I see performance improvement.

With kernel 3.4.5 I can reach maximum od 7.5Mpps with my hardware
And with kernel 3.5.0-rc7-next-20120720 i can reach 8.2Mpps - forwarding 
UDP performance - can be more - but my TX pktgen that use 6 cores can't 
do more.

Really thanks for this :)
