Module Name:    src
Committed By:   knakahara

Modified Files:
        src/sys/netinet: ip_flow.c ip_var.h

Log Message:
improve fast-forward performance when the number of flows exceeds IPFLOW_MAX.

In the fast-forward case, when the number of flows exceeds IPFLOW_MAX, the
performmance degraded to about 50% compared to the case less than IPFLOW_MAX
flows. This modification suppresses the degradation to 65%. Furthermore,
the modified kernel is about the same performance as the original kernel
when the number of flows is less than IPFLOW_MAX.

The original patch is implemented by ryo@n.o. Thanks.
