Why DSA exposes the CPU port as the real bottleneck — and how a topology-aware multi-queue NIC design fixes head-of-line blocking.
Why DSCP, switch QoS and Wi-Fi WMM don’t align — and how to build a consistent QoS model that actually works.
Why Wi-Fi bridging behaves differently from Ethernet switching — and how technologies like MediaTek WED are changing the datapath.
Why the classic “switch vs bridge” explanation breaks down in Linux — and how DSA merges both into a single model.
What the Linux bridge really is, why it is not a switch, and how DSA turns it into a powerful hardware-offloaded networking model.
Why hardware QoS disappeared from Linux routers and why it is returning in modern datacenter networks — and even older SoHo routers.
