2015-01-16net/vsc9953: Add driver for Vitesse VSC9953 L2 Switch IPCodrin Ciubotariu
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 Signed-off-by: Codrin Ciubotariu <codrin.ciubotariu@freescale.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: York Sun <yorksun@freescale.com>
