This patch set adds several features for VSC9953 L2 Switch:
	- VLAN configuration;
	- port statistics;
	- FDB table operations;
	- enable/disable HW learning;
	- private/shared VLAN learning.

Also, the parser needed to be changed to allow commands
with optional parameters and to allow developers to easily
add new commands.

Since new features are added, the default configuration
had to be changed to:
	- HW learning enabled on all ports; (HW default)
	- All ports are in VLAN 1;
	- All ports are VLAN aware;
	- All ports have POP_COUNT 1;
	- All ports have PVID 1;
	- All ports have TPID 0x8100; (HW default)
	- All ports tag frames classified to all VLANs that are not PVID;

If the user decides to compile the VSC9953 driver without the support
for commands, the above default configuration should be sufficient
to make the L2 Switch work in unmanaged mode.

New supported commands:
	- show a port's statistics;
	- enable/disable/show learning configuration on a port;
	- add/delete a MAC entry in FDB; show the FDB table;
	- add/remove a VLAN to/from a port (VLAN members);
	- set/show PVID (ingress and egress VLAN tagging) for a port;
	- set egress tagging mod for a port;
	- configure VID source for egress tag;
	- make VLAN learning shared or private;
	- enable/disable VLAN ingress filtering on a port.

This patch groups some macros defined for registers and
replaces some magic numbers from vsc9953 with macros. Also,
"port" and "port_nr" keywords are replaced with "port_no".

Also, in some places, this patch replaces in_le32 and out_le32
with clrbits_le32 and setbits_le32 to reduce the number of code
lines and to assure that only intended bits of a register are
changed.

  To: u-boot

At startup, the default configuration should be:
 - enable HW learning on all ports (HW default);
 - all ports are VLAN aware;
 - all ports are members of VLAN 1;
 - all ports have Port-based VLAN 1;
 - on all ports, the switch is allowed to remove
   maximum one VLAN tag,
 - on egress, the switch should add a VLAN tag if the
   frame is classified to a different VLAN than the port's
   Port-based VLAN;

  To: u-boot

In order to support multiple commands to configure the VSC9953
L2 Switch, the parser needs to be changed to be more flexible and
to support more complex commands. This patch adds a parser that
searches for defined keywords in the command and calls the proper
function when a match is found. Also, the parser allows for
optional keywords, such as "port", to apply the command on a port
or on all ports. The already defined commands are also changed a
bit to:
ethsw [port <port_no>] { enable | disable | show }

  To: u-boot

The new added command:
ethsw [port <port_no>] statistics { [help] | [clear] }

will print counters like the number of Rx/Tx frames,
number of Rx/Tx bytes, number of Rx/Tx unicast frames, etc.

  To: u-boot

The new command:
ethsw [port <port_no>] [vlan <vid>] fdb
	{ [help] | show | flush | { add | del } <mac> }

Can be used to add and delete FDB entries. Also, the command can be used
to show entries from the FDB tables. When used with [port <port_no>]
and [vlan <vid>], only the matching the FDB entries can be seen or
flushed.

The new added commands can be used to configure VLANs for a port
on both ingress and egress.

The new commands are:
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 mod 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

The command:
ethsw vlan fdb { [help] | show | shared | private }
 - make VLAN learning shared or private"

configures the FDB to share the FDB entries learned on multiple VLANs
or to keep them separated. By default, the FBD uses private VLAN
learning.

The command:
ethsw [port <port_no>] ingress filtering
     { [help] | show | enable | disable }
  - enable/disable VLAN ingress filtering on port

can be used to enable/disable/show VLAN ingress filtering on a port.

This patch set adds several features for VSC9953 L2 Switch:
	- VLAN configuration;
	- port statistics;
	- FDB table operations;
	- enable/disable HW learning;
	- private/shared VLAN learning.

Also, the parser needed to be changed to allow commands
with optional parameters and to allow developers to easily
add new commands.

Since new features are added, the default configuration
had to be changed to:
	- HW learning enabled on all ports; (HW default)
	- All ports are in VLAN 1;
	- All ports are VLAN aware;
	- All ports have POP_COUNT 1;
	- All ports have PVID 1;
	- All ports have TPID 0x8100; (HW default)
	- All ports tag frames classified to all VLANs that are not PVID;

If the user decides to compile the VSC9953 driver without the support
for commands, the above default configuration should be sufficient
to make the L2 Switch work in unmanaged mode.

New supported commands:
	- show a port's statistics;
	- enable/disable/show learning configuration on a port;
	- add/delete a MAC entry in FDB; show the FDB table;
	- add/remove a VLAN to/from a port (VLAN members);
	- set/show PVID (ingress and egress VLAN tagging) for a port;
	- set egress tagging mod for a port;
	- configure VID source for egress tag;
	- make VLAN learning shared or private;
	- enable/disable VLAN ingress filtering on a port.
