+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)
