[U-Boot] [PATCH v2 05/11] net/vsc9953: Add driver for Vitesse VSC9953 L2 Switch IP

Fri Dec 19 18:02:03 CET 2014
This patch adds a driver for VSC9953 L2 Switch. This Vitesse IP
is integrated in Freescale T1040 and T1020 SoCs.
The L2 switch has 10 Ethernet ports: 2 internal fixed-links
(ports 8 and 9) at 2.5 Gbps and and 8 external ports at 1 Gbps.
The external ports may be connected to PHYs over QSGMII and SGMII.
Commands have also been added to enable/disable a port and to
check a port's link speed, duplexity and status. The commands are:
ethsw port <port_nr> enable|disable - enable/disable an l2 switch port
ethsw port <port_nr> show - show an l2 switch port's configuration
port_nr=0..9; use "all" for all ports
For more detailse please see doc/README.t1040-l2switch

+This file contains information for VSC9953, a Vitesse L2 Switch IP
+which is integrated in the T1040/T1020 Freescale SoCs.
+
+About Device:
+=============
+VSC9953 is an 8-port Gigabit Ethernet switch supports the following features:
+ - 8192 MAC addresses
+ - Static Address provisioning
+ - Dynamic learning of MAC addresses and aging
+ - 4096 VLANs
+ - Independent and shared VLAN learning (IVL, SVL)
+ - Policing with storm control and MC/BC protection
+ - IPv4 and IPv6 multicast
+ - Jumbo frames (9.6 KB)
+ - Access Control List
+ - VLAN editing, translation and remarking
+ - RMON counters per port
+
+Switch interfaces:
+ - 8 Gigabit switch ports (ports 0 to 7) are external and are connected to external PHYs
+ - 2 switch ports (ports 8 and 9) of 2.5 G are connected (fixed links)
+ to FMan ports (FM1 at DTSEC1 and FM1 at DTSEC2)
+
+Commands Overview:
+=============
+Commands supported
+ - enable/disable a port
+ - check a port's link speed, duplexity and status.
+
+Commands syntax
+ ethsw port <port_nr> enable|disable - enable/disable an l2 switch port
+ ethsw port <port_nr> show - show an l2 switch port's configuration
+
+ port_nr=0..9; use "all" for all ports
+
+=> ethsw port all show
+ Port Status Link Speed Duplex
+ 0 enabled down 10 half
+ 1 enabled down 10 half
+ 2 enabled down 10 half
+ 3 enabled up 1000 full
+ 4 disabled down - half
+ 5 disabled down - half
+ 6 disabled down - half
+ 7 disabled down - half
+ 8 enabled up 2500 full
+ 9 enabled up 2500 full
