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

Changes for v2:

• added debug messages if MDIO reads or writes timeout;
• added debug messages when reset of VSC9953 switch fails;
• replaced Copyright and license to the generic one;

Changes for v3: Removed "Change-id" line from comment;

+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@DTSEC1 and FM1@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
