This section describes changes that affect networking in FreeBSD.
+For {{< manpage "tcp" "4">}}, Proportional Rate Reduction, as described by RFC6937, to improve SACK loss recovery during burst loss and ACK thinning scenarios, was implemented and is enabled by default.
+It is expected that PRR generally helps improve loss recovery performance and prevent numerous preventable RTO stalls.
+This surpasses the prior behavior, but a strictly packet conserving variant can be enabled.
+When misconfigured token bucket traffic policer can persistent loss even during loss recovery, activating the conservative PRR variant may prevent some RTOs while behaving less optimal in the general case. {{< commit "0e1d7c25c5ab" >}} {{< sponsored "NetApp" >}}
+
+The {{< manpage "cc_cubic" "4">}} has been improved to address various corner cases and align more closely with the standard in RFC8312. {{< commit "40f9078ff9d9" >}} {{< sponsored "NetApp" >}}
+
+The {{< manpage "ping" "8" >}} and {{< manpage "ping6" "8" >}} utilities both support setting network QoS, with IP DSCP {{< commit "6034024daddb" >}} and Ethernet PCP {{< commit "81a6f4c7ae69" >}} {{< sponsored "NetApp" >}}
