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@DTSEC1 and FM1@DTSEC2)

Commands Overview:
=============
Commands supported
	- enable/disable a port or show its configuration (speed, duplexity, status, etc.)
	- port statistics
	- MAC learning
	- add/remove FDB entries
	- Port-based VLAN
	- Private/Shared VLAN learning
	- VLAN ingress filtering
	- Port LAG

Commands syntax
ethsw [port <port_no>] { enable | disable | show } - enable/disable a port; show a port's configuration
ethsw [port <port_no>] statistics { [help] | [clear] } - show an l2 switch port's statistics
ethsw [port <port_no>] learning { [help] | show | auto | disable } - enable/disable/show learning configuration on a port
ethsw [port <port_no>] [vlan <vid>] fdb { [help] | show | flush | { add | del } <mac> } - add/delete a mac entry in FDB; use show to see FDB entries;
											  if [vlan <vid>] is missing, VID 1 will be used
ethsw [port <port_no>] pvid { [help] | show | <pvid> } - set/show PVID (ingress and egress VLAN tagging) for a port
ethsw [port <port_no>] vlan { [help] | show | add <vid> | del <vid> } - add a VLAN to a port (VLAN members)
ethsw [port <port_no>] untagged { [help] | show | all | none | pvid } - set egress tagging mode for a port
ethsw [port <port_no>] egress tag { [help] | show | pvid | classified } - configure VID source for egress tag.
									  Tag's VID could be the frame's classified VID or the PVID of the port
ethsw vlan fdb { [help] | show | shared | private } - make VLAN learning shared or private
ethsw [port <port_no>] ingress filtering { [help] | show | enable | disable } - enable/disable VLAN ingress filtering on port
ethsw [port <port_no>] aggr { [help] | show | <lag_group_no> } - get/set LAG group for a port
