+description: |+
+   The Microchip Sparx5 SoC is a ARMv8-based used in a family of
+   gigabit TSN-capable gigabit switches.
+
+   The SparX-5 Ethernet switch family provides a rich set of switching
+   features such as advanced TCAM-based VLAN and QoS processing
+   enabling delivery of differentiated services, and security through
+   TCAM-based frame processing using versatile content aware processor
+   (VCAP)
