* systemd-networkd gained support for configuring Token Buffer Filter
* systemd-networkd gained support for configuring Token Bucket Filter
(TBF) parameters in its qdisc configuration support. Similar, support
for Stochastic Fairness Queuing (SFQ), Controlled-Delay Active
Queue Management (CoDel), Fair Queue (FQ) has been added.
