sys/netinet ip_flow.c ip_input.c
Log:
Parallelize ip_flow:
- Create per-CPU ipflow hash table. During initial ipflow installation, route
entry to the destination is allocated on each CPU and cached in the ipflow,
so each CPU will only access the route entry owned by itself.
- Timeout processing on per-CPU ipflow hash table is initialized by
broadcasting
IPI to each CPU. In IPI, a per-CPU netmsg is used to inform CPU local
netisr
to do the real timout processing.
- Add sysctl node to show how many ipflow entries are used on the each CPU.
