TLB shootdown for mapping on buffer creation and reuse, greatly reducing the

of the system time on i/o intensive workloads.</para>

<para revision="227614">&man.netmap.4; has been added. &man.netmap.4; is a framework for
high-performance direct-to-hardware packet IO, offering low latency and high PPS
rates to userland applications while bypassing any kernel-side packet processing.
With &man.netmap.4; it is trivially possible to fully saturate a 10 Gbps network interface with
minimal packet sizes. For more information, see:
