The patches mainly finish following functions:
1) Store and restore all kinds of filters.
2) Parse all kinds of filters.
3) Add flow validate function.
4) Add flow create function.
5) Add flow destroy function.

The whole patch set is related to filter, so do you think it's better to move the patch from his patch set since it's related to configuration? Please help to check.

Why do you declare cons_parse_ntuple_filter here? And seems it doesn't align with the name rule.

Why do you define the function in PMD with rte_ prefixed? Do you want to move it to rte library?

How about splitting the function into three functions? Including parse pattern/parse actions/parse attr.

Why do u remove functions added in patch 14/18? If the functions don't be needed, how about changing patch 14/18?

Why need to define these structures? There has been structures to store the filter before, isn't it?

This patch is generate in a very complicated way.
If you go on reading this patch, you will find the following statement, path add the functions back itself latter
So the git seem to generate a patch in a peculiar way.
+static int
+cons_parse_l2_tn_filter(const struct rte_flow_attr *attr,
+ const struct rte_flow_item pattern[],
+ const struct rte_flow_action actions[],
+ struct rte_eth_l2_tunnel_conf *filter,

This patch is generate in a very complicated way.
If you go on reading this patch, you will find the following statement, path add the functions back itself latter
So the git seem to generate a patch in a peculiar way.

Should the return statement be in the parantheses above?

Before return NULL, ixgbe_flow_mem_ptr and flow should be freed, right?
And ixgbe_flow_mem_ptr should be removed from ixgbe_flow_list. Or you can move TAILQ_INSERT_TAIL(&ixgbe_flow_list, ixgbe_flow_mem_ptr, entries) after a flow is added successfully.
Same comments for "return NULL" below.

See my previous reply [1], this definition is not endian-safe and comprises
protocols defined as independent items (namely ETH and VLAN). Here is an
untested suggestion:
struct rte_flow_item_e_tag {
uint16_t tpid; /**< Tag protocol identifier (0x893F). */
/** E-Tag control information (E-TCI). */
uint16_t epcp_edei_in_ecid_b; /**< E-PCP (3b), E-DEI (1b), ingress E-CID base (12b). */
uint16_t rsvd_grp_ecid_b; /**< Reserved (2b), GRP (2b), E-CID base (12b). */
uint8_t in_ecid_e; /**< Ingress E-CID ext. */
uint8_t ecid_e; /**< E-CID ext. */
};
Applications are responsibile for breaking down and filling individual
fields properly. Ethernet header would be provided as its own item as shown
in this testpmd flow command example:
flow create 0 ingress pattern eth / e_tag in_ecid_base is 42 / end actions drop / end
Note, all multibyte values are in network order like other protocol header
definitions.

See my previous reply [1], this definition is not endian-safe due to the use
of bit-fields and should look more like the VXLAN item. Here is an untested
suggestion (not sure about all values):
struct rte_flow_item_nvgre {
/**
* Checksum (1b), undefined (1b), key bit (1b), sequence number (1b),
* reserved 0 (9b), version (3b).
*
* \c_k_s_rsvd0_ver must have value 0x2000 according to RFC 7637.
*/
uint16_t c_k_s_rsvd0_ver;
uint16_t proto; /**< Protocol type (0x6558). */
uint8_t vsid[3]; /**< Virtual subnet ID. */
uint8_t flow_id; /**< Flow ID. */
};
Like for E-Tag, applications are responsibile for breaking down and filling
individual fields properly.

Hi, Wei Zhao
Would you please do git rebase master for this patch set?
When I do git pull and then git apply this patch, following errors are reported:
[root@dpdk4 dpdk-org]# git am ../patches/bundle-488-zhaowei-ixgbe-filter-api-v2.mbox
Applying: net/ixgbe: store SYN filter
Applying: net/ixgbe: store flow director filter
error: patch failed: drivers/net/ixgbe/ixgbe_ethdev.c:1284
error: drivers/net/ixgbe/ixgbe_ethdev.c: patch does not apply
Patch failed at 0002 net/ixgbe: store flow director filter
The copy of the patch that failed is found in: .git/rebase-apply/patch
When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".

Hi, Wei Zhao
I think that you had better give a cover letter for such a series of patches.
You can give the changes between v2 and v1 in cover letter
and maybe no need describe it in each one.
Thanks &Best Regards

In this case , is eth an option or mandatory?
I think it is optional, because user may do not have any parameter in ETH config.

Normally, protocol items start from L2 so applications *should* provide
ETH otherwise it is an error.
Now a PMD may also allow it to be implicit when it is unambiguous (e.g. an
imaginary ETH item provided without a mask) as described in the "UDPv6
anywhere" example [2]. It's up to you.

I think you have mentioned in previous review that you will update this

I think it is good idea to move all rte_flow related code into a new
file, as done in i40e (i40e_flow.c)? What do you think, can it be done?

It would be nice to comment here valid/expected pattern values
(spec/mask/last). Otherwise it is hard to decode from code also it is
good to document intention, so makes easy if there is any defect.
Also valid actions.

Sometimes meset filter before return from error, sometimes not. Is
memset required at all?

Although there is no harm, I would do input check at the beginning of

May be good idea to check if attr is NULL.

Is memset required for error cases, if so is other error cases also
require it?

Not sure about this log here, specially it is in ERR level.
This function is returning error, and public API will return an error,
if we want to notify user with a log, should app do this as library
(here) should do this? More comment welcome?
btw, should rte_flow_error_set() used here (and below) ?

It is possible to rename this struct to rte_flow, to prevent casting.
Although functionally there is no difference.

The patches mainly finish following functions:
1) Store and restore all kinds of filters.
2) Parse all kinds of filters.
3) Add flow validate function.
4) Add flow create function.
5) Add flow destroy function.
6) Add flow flush function.
v2 changes:
fix git log error
Modify some function call relationship
Change return value type of all parse flow functions
Update error info for all flow ops
Add ixgbe_filterlist_flush to flush flows and rules created
v3 change:
add new file ixgbe_flow.c to store generic API parser related functions
add more comment about pattern and action rules
add attr check in parser functions
change struct name ixgbe_flow to rte_flow
change SYN to TCP SYN
change to use memset initizlize struct ixgbe_filter_info
break down filter uninit process to 3 indepedent functions in eth_ixgbe_dev_uninit()
change struct rte_flow_item_nvgre definition
change struct rte_flow_item_e_tag definition
fix one bug in function ixgbe_dev_filter_ctrl
add goto in function ixgbe_flow_create
delete some useless initialization
eliminate some git log check warning

The patches mainly finish following functions:
1) Store and restore all kinds of filters.
2) Parse all kinds of filters.
3) Add flow validate function.
4) Add flow create function.
5) Add flow destroy function.
6) Add flow flush function.
v2 changes:
fix git log error
Modify some function call relationship
Change return value type of all parse flow functions
Update error info for all flow ops
Add ixgbe_filterlist_flush to flush flows and rules created
v3 change:
add new file ixgbe_flow.c to store generic API parser related functions
add more comment about pattern and action rules
add attr check in parser functions
change struct name ixgbe_flow to rte_flow
change SYN to TCP SYN
change to use memset initizlize struct ixgbe_filter_info
break down filter uninit process to 3 indepedent functions in eth_ixgbe_dev_uninit()
change struct rte_flow_item_nvgre definition
change struct rte_flow_item_e_tag definition
fix one bug in function ixgbe_dev_filter_ctrl
add goto in function ixgbe_flow_create
delete some useless initialization
eliminate some git log check warning
v4 change:
fix some check patch warning

Although this is static function, you may prefer to keep ixgbe_
namespace in the function.

This documents item.type, can you please also document expected/valid
item->spec, item->last and item->mask values.
Same for all parse functions.
I am aware this is lots of comment when you think all parse functions,
but I believe this can be very useful in the future.
And it is very unlikely that it will be done later, if it has not been
done now.

These are syntax modification to the updates added in previous patch.
They can be fixed when they added at first place.

Overall patchset looks good, only major comment is adding more comments
on parse_filter functions for expected/valid rules.
You can keep Beilei's Ack for next version of the patchset.

Hi Adrien,
Can you please review rte_flow related part of the patch below?
I am OK with rest of the patch, and planning to apply to next-net if you
don't have any objection.
Thanks,

OK for these definitions, however API documentation
(doc/guides/prog_guide/rte_flow.rst) must be kept up to date, and it would
be great if testpmd support for these new items was added simultaneously
(changes in app/test-pmd/cmdline.c, app/test-pmd/cmdline_flow.c and
doc/guides/testpmd_app_ug/testpmd_funcs.rst).
How about putting all rte_flow changes (API & testpmd) in their own separate
patch?
You could use VLAN PCP/DEI/VID definitions as an example to expose partial
bit-fields (e.g. epcp_edei_in_ecid_b) in testpmd, see:
1419fd5a6c9f ("app/testpmd: add protocol fields to flow command")
Now if re-spinning this series yet again is too much work, you can go ahead
with this commit as long as you do not forget to submit the rest later,
thanks.

I thought it can be more useful to have library and its user updated in
same patch, gives more context. But missed rte_flow documentation ...

Is following todo list complete:
1- update rte_flow document, doc/guides/prog_guide/rte_flow.rst,
document two new item types: E_TAG & NVGRE.
2- Add testpmd sample implementation and documentation.
Hi Wei,
Would you mind working on a patch to cover above items?

Not much of an issue as long as it's updated, also I did not notice the
series was already applied before replying.

Right, everything at once in a single patch is fine. The existing item
definitions and testpmd commands can be used as templates.

I am sorry for miss rte_flow.rst document update, I DON'T know there is such a new file of rte_flow.rst.
And also these two types of E_TAG & NVGRE are added into code after rte_flow patch,
So testpmd implementation do not support for these type.
Now, we have been work on task of 17.05.
How about finish (1) first as one patch, then after busy work of 17.05 to add (2) as another patch?
OR, if these two work merge in to patch set, I will may be begin to do after the 17.05 task finish?
Which one is OK for you?
Thank you.

Changes can be in two separate patches, and if possible, can this get
priority against 17.05 task?
This is for 17.02 feature and not completely finished, missing for last
touches..

Add testpmd implementation example is not in our plan from the begin of the task generic filter API by us,
Because all this part is not covered by us(intel) when task allocation.
BUT if this component is need by community, I will report to my leader and add it into our next work plan and try to finish it ASAP.

Yes please, I believe it is needed.
