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.

Changes for v2:
	- removed Change-id field;
	- Added the patch that changes the License
	at the end of the patch set for an easier
	integration;

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.

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;

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 }

From: Codrin Ciubotariu @ 2015-06-23 16:48 UTC (permalink / raw)
  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.

Is it reasonable to use values from asm/errno.h here and elsewhere in
the driver? This seems like it should return -ENODEV instead of
-EPERM.

This is incorrect... Should be:

All of there that are register constants should not have "CONFIG_"
prepended to them. That should only be for constants that configure
something, eventually only from Kconfig.  Please add another patch
before this one that removes that.

May as well get rid of the tabs here after the defines.

Yes, I should use values from errno.h . -ENOMEM seems more appropriate to me. What do you think?

Ok, I will add another patch before this one.

Ok.

Thank you for your review. I will make v3.

Yes, sorry. I didn't look at the line above! :/

Maybe this:

If you accept the above, you need to change these to:
+       if (vsc9953_vlan_table_poll_idle() < 0) {

or

+       if (vsc9953_vlan_table_poll_idle() == -EBUSY) {

It seems this could if statement could all be simplified as:
+       clrsetbits_le32(&l2ana_reg->ana_tables.vlan_access,
+                       CONFIG_VSC9953_VLAN_PORT_MASK |
+                       CONFIG_VSC9953_VLAN_CMD_MASK,
+                       field_set(CONFIG_VSC9953_VLAN_CMD_WRITE,
+                                 CONFIG_VSC9953_VLAN_CMD_MASK) |
+                       (set ? CONFIG_VSC9953_VLAN_PORT_MASK : 0));

It may also help to rename the parameter from "set" to something like
"set_member".

This seems like the naming is inverted. The enum value is called
"untag" pvid and zero, but the config is called "tag" all pvid and
zero. Is this a bug or just poorly named constants / enum values?

I don't follow why this is unique to this chip? Also, get is never
used. Is it just for completeness, I assume.

I think you should either be using the functions in include/bitfield.h
or you should be adding these there instead of here. If you decide to
add them there, then naturally do it as a separate patch and with good
comments and naming consistent with that file and as functions not
macros. This method is nice in that you use the mask to define the
shift instead of requiring it as a separate constant.

Seems like you should drop the "port_" from all of these member names.

These comments seem gratuitous and not particularly relevant (begin
and end). Perhaps either remove them throughout the file or at least
don't add more. At the very least, drop the " structure for T1040
U-boot" which isn't helpful or accurate.

I'd like to see this moved to its own file in common... maybe
"common/cmd_ethsw.c". I'd also like to see this #define change to
something like "CONFIG_CMD_ETHSW".

These changes don't necessarily need to be part of this series, since
it already got in as is, but if you feel motivated, I would recommend
you add a patch before this one that moves it.

+               rc = CMD_RET_USAGE;

Use this:
+       rc = keywords_find(argc, argv, &parsed_cmd);
+       if (rc)
+               goto __ret_cmd_cleanup;

I think this whole if statement is unneeded since this same test
already exists in keywords_find().

Remove this if statement along with parsed_cmd.err.

Use a single space. Place each variable on its own line.

It seems like masking off the val before shifting it would be better
implemented inside the field_get function (renamed and moved to
include/bitfield.h) instead of on each use.

Use this:

I recently made a pass through U-Boot trying to standardize on that
naming. Also, don't make it a pointer that has to be allocated. It is
small and of known size.

This functionality is already implemented in common/env_flags.c in the
_env_flags_validate_type() function. Maybe that implementation should
be extracted.  Another option is to make the eth_parse_enetaddr() in
net/eth.c return a status and then it can be used. Either way I don't
think it should be re-implemented here.

Why malloc this? It is small and known size.

Don't malloc, and you don't need free.

By mistake. I will remove the extra pair.

Ok, I will make sure there are no tabs after a variable's type, in all these patches.

Yes, the naming is inverted. The main reason for this is that I couldn't
find a short and easy to use command to configure a port's egress to send
all frames VLAN tagged except when the VLAN ID equals the Port VLAN ID.
I decided to make a command to tell the switch for which VLAN ID's not to
tag a frame (untag) instead of making a command to tell the switch for
which VLAN IDs to tag the frame (tag). So, for example, the command
"ethsw [port <port_no>] tag all except pvid" or
"ethsw [port <port_no>] tag !pvid" became
"ethsw [port <port_no>] untagged pvid". If you think this is not intuitive
for both users and developers, I will try to find something more appropriate.

These are not unique to this chip. If you consider them useful, I will
make a separate patch and add them (or something similar) to
include/bitfield.h . I could also use those from bitfield.h, but then I
should create new macros or use some sort of magic numbers for the
"shift" parameter. Changing the already defined bitfiled_*() functions
doesn't look like an option since it would require changes all over
u-boot.

Yes, I will remove the "port_".

Yes, the " structure for T1040 U-boot" seems irrelevant indeed. I will
also remove the other comments if you consider them unnecessary. To me
it looks like it groups the structures a bit and might help developers
look for a specific register. I will remove them in the patch with the
clean-up.

Thanks and best regards,

I don't have a problem with using the inverted logic if that's what
typical use-cases call for, what I was referring to was those two
specific examples. The "all" and "none" seem correctly inverted.

In the other 2 cases, the "tag" vs "untag" is inverted, but the
subject is not "PVID_AND_ZERO" vs "ALL_PVID_ZERO"

"EGRESS_UNTAG_PVID_AND_ZERO" ->
"CONFIG_VSC9953_TAG_CFG_ALL_PVID_ZERO", for example. That's the
discrepancy I'm concerned about.

I think this would be the best approach.

That could be done, but if you do create macros for the shift
parameter, they should go in bitfield.h.

Please do not add magic numbers.

Yes, certainly do not do this. Use them as is or add new versions. Do
no change the existing functions.

If you think the bracketing of these structs adds clarity, then only
remove the trailing text. Otherwise remove all of them completely. Up
to you; I'm fine with either way.

Ok, should I rename the constants to something like VSC9953_TAG_CFG_ALL_BUT_PRIV_ZERO instead of CONFIG_VSC9953_TAG_CFG_ALL_PVID_ZERO and VSC9953_TAG_CFG_ALL_BUT_ZERO instead of CONFIG_VSC9953_TAG_CFG_ALL_ZERO?

Ok, I will make another patch and add bitfield_set/get() inline functions in include/bitfield.h .

I could move this parser in common/do_ethsw.c and rename the define. I guess this would imply that upcoming drivers for Ethernet L2 Switches could use the same commands while calling their specific functions.

Ok, I wasn't aware of these macros. I will make use them in this patch set when it's appropriate.

Ok. I will also make the changes along this patch to check it?s return code.

This function is populated later by another patch and it frees a dynamically allocated buffer. You suggested to use a static buffer instead, so I guess I will remove this functions since it's no longer needed.

Yes, something like #define field_set(val, mask)           (((val) * ((mask) & ~((mask) << 1))) & mask) and
#define field_get(val, mask)           ((val & mask) / ((mask) & ~((mask) << 1))).

To assure that the shifted vid value is not higher than its mask. Adding the mask to the macro/inline function as described above should assure this.

is_valid_ethaddr() returns false if the mac address is 00:00:00:00:00:00, but for the L2 Switch, this mac address is valid. Maybe is_broadcast_ethaddr()?

Yes, I noticed that this function is already implemented, but with no access to it. I will see how I can use the one available.

I will declare the array statically.

I added it here so that vsc9953_port_vlan_pvid_get() could be next to its pair, vsc9953_port_vlan_pvid_set(). If you think that it should be at the bottom of the file I can move it.

By mistake, I will remove one pair.

> > +#ifdef CONFIG_VSC9953_CMD
> 
> Why does this need to be defined outside of the #ifdef already at the
> bottom of the file?

I did this so that similar get/set() functions to be close to one another. Also, the functions guarded by CONFIG_VSC9953_CMD are used only when the ethsw commands are enabled (CONFIG_VSC9953_CMD defined). If a user decides to use the driver for VSC9953, with the switch working in unmanaged state and he doesn't need the commands to configure the switch, he could compile u-boot with CONFIG_VSC9953_CMD undefined. In this case, some warnings will appear at compile time suggesting that functions like vsc9953_port_vlan_egr_untag_get() are defined but not used.

Yes, it's a typo.

Hi Joe,

I will make a v3 with your suggestions.

Thanks and best regards,
Codrin

I assume you meant to say VSC9953_TAG_CFG_ALL_BUT_*PVID*_ZERO here.

If so, I think that's clear enough.

I would recommend you structure it as 3 new functions.

That's the idea. It would be great to keep it semi-generic.

The set seems the same as replace, just without any other bitfields to
preserve. You could just use replace and pass in 0 as the reg_val.

OK. Maybe the existing bitfield_replace() should be updated to also
mask off the bitfield_val.

I'm not sure what criteria you intend to check for here, so I'm not
sure if that is appropriate.

Which path do you plan to take?

OK, I think that makes sense the way you had it. Also, it wouldn't
make sense to move out of drivers/net/vsc9953.c, so leave it here.

Also, the functions guarded by CONFIG_VSC9953_CMD are used only when the ethsw commands are enabled (CONFIG_VSC9953_CMD defined). If a user decides to use the driver for VSC9953, with the switch working in unmanaged state and he doesn't need the commands to configure the switch, he could compile u-boot with CONFIG_VSC9953_CMD undefined. In this case, some warnings will appear at compile time suggesting that functions like vsc9953_port_vlan_egr_untag_get() are defined but not used.

Sounds good. You can leave this here.

Thanks,
-Joe

Ok, should we assure we return 0 if mask is 0? Something like return mask : ffs(mask) - 1 ? 0;

Yes, although I still have to pass the "shift" parameter.

Yes, I think it should be updated. Should I make a separate patch for it? It should be out of this patch set since it has nothing to do with VSC9953.

When a command for adding/removing a mac address is issued, we should check if there is a valid mac address in parsed_cmd->mac_addr. I guess that this could be checked only in keyword_match_mac_addr(). Also, since mac_addr will become a static array, I should initialize this array with an invalid mac address. Since 0 mac address is a valid address for the L2 Switch, I was thinking to initialize it with L2 Broadcast address. What do you think?

I looked through both eth_parse_enetaddr() and _env_flags_validate_type() and I prefer the implementation from the latter function, since eth_parse_enetaddr() doesn't check for ':' or if the value returned by simple_strtoul() is <= 0xFF. I could move the code from "case env_flags_vartype_macaddr:" to a separate function (something like eth_check_enetaddr()? ) and add its prototype somewhere in include/net.h. What do you think?

Hi Joe,

> 
> Why is this value changing? Was it just wrong before?
Sorry, I missed this comment. Yes, the correct value that only enables the port is 0x00002000. The rest of the bits are set to 1 because they are reserved and default values. Since this patch changes the way l2qsys_reg->sys.switch_port_mode[i] is set (out_le32() replaced by setbits_le32()), the other bits are no longer touched when enabling the port:
-		out_le32(&l2qsys_reg->sys.switch_port_mode[i],
-			 CONFIG_VSC9953_PORT_ENA);
+		setbits_le32(&l2qsys_reg->sys.switch_port_mode[i],
+			     CONFIG_VSC9953_PORT_ENA)

Should I make a different patch for this change?

Best regards,
Codrin

I also need to create a do_ethsw.h that should contain at least struct keywords_to_function. I need this so that any driver could set its implementation in .keyword_function. Where should I put this header?

I think you should add a file simply called "include/ethsw.h"

Not if you use the new bitfield_replace_by_mask().

Definitely a separate patch.

I guess that this could be checked only in keyword_match_mac_addr(). Also, since mac_addr will become a static array, I should initialize this array with an invalid mac address. Since 0 mac address is a valid address for the L2 Switch, I was thinking to initialize it with L2 Broadcast address. What do you think?

Sounds good.

I think it should be called eth_validate_ethaddr_str(). You can add it
to include/net.h and the top of net/eth.c
