sky2: no recycling
Recycling turns out to be a bad idea! For most use cases, the packet can not be reused: TCP packets are cloned. Even for the ideal case of forwarding, it hurts performance because of CPU ping/pong. On a multi-core system forwarding of 64 byte packets is worse much worse: recycling = 24% forwarded vs no recycling = 42% forwarded Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.
