-title: Lantiq GSWIP Ethernet switches
+title: Lantiq GSWIP and MaxLinear GSW1xx Ethernet switches
+
+description:
+  Lantiq GSWIP and MaxLinear GSW1xx switches share the same hardware IP.
+  Lantiq switches are embedded in SoCs and accessed via memory-mapped I/O,
+  while MaxLinear switches are standalone ICs connected via MDIO.
