<title>Network Protocols</title>
<para>The <literal>ip_flow</literal> feature in the IPv4 protocol
implementation has been replaced by the
<literal>ip_fastforward</literal> feature.
<literal>ip_fastforward</literal> attempts to speed up simple
cases of packet forwarding, processing a forwarded packet to
an outgoing interface without queues or netisrs. If it cannot
handle a particular packet, it passes that packet to the normal
<literal>ip_input</literal> routines for processing. This
feature can be enabled by setting the
<varname>net.inet.ip.fastforwarding</varname> sysctl variable
to <literal>1</literal>.
<para>The <literal>IP_ONESBCAST</literal> option has been added
to enable undirected &man.ip.4; broadcasts to be sent to
specific network interfaces.</para>
