Hi Beilei,
I think the commit title should reflect that this commit adds support for
GRE and MPLS items to rte_flow, testpmd changes are only a consequence.

Same comments about RTE_FLOW_ITEM_TYPE_NVGRE added by another series. You
should mention there's a dependency between them.

Hi Beilei,
Can you please help me to understand what has been replaced here, and why?
Thanks,

* Cloud filters type is a combination of up to 3 L1 filters.
* L1 filter depends on Type Rule index.
First, there's no MPLS label as L1 filter currently, so we need to add MPLS label by replacing some existing L1 filter, here we replace IMAC.
Second, there's no MPLS label as cloud filter currently, So here we add a new cloud filter type TEID_MPLS (0x11) to replace Inner MAC filter(0xA).
According to datasheet, the following filter types are supported by cloud filter.
6:0: Filter type:
* 0x0: Reserved
* 0x1: Reserved
* 0x2: Reserved
* 0x3: Inner MAC, Inner VLAN (for NVGRE, VXLAN or, Geneve or VXLAN-GPE packets)
* 0x4: Inner MAC, Inner VLAN, Tenant ID (for NVGRE, VXLAN, or Geneve or VXLAN-GPE
packets)
* 0x5: Reserved
* 0x6: {Inner MAC, Tenant ID} (NVGRE packet, or VXLAN, /Geneve or VXLAN-GPE packets).
* 0x7: Reserved
* 0x8: Reserved
* 0x9: Outer MAC L2 filter
* 0xA: Inner MAC filter
* 0xB: Outer MAC, Tenant ID, Inner MAC
* 0xC: Application Destination IP
* 0xD: Application Source-IP, Inner MAC.
* 0xE - 0x3F: Reserved.

No, I40E_AQC_REPLACE_CLOUD_CMD_INPUT_FV_IMAC is L1 filter, but the I40E_AQC_ADD_CLOUD_FILTER_IIP is cloud filter.
We should replace L1 filter here.

> We should replace L1 filter here.
The I40E_AQC_REPLACE_CLOUD_CMD_INPUT_FV_IMAC macro (value 12) is an index into the Field Vector, it is not a filter type macro.
Should a filter type macro be used to set filter_replace.old_filter_type ?

This patchset adds support for MPLSoGRE and MPLSoUDP
tunnel filters.
I40e NICs can't recongnize MPLS tunnel packets by
default, so need to load a profile to FW first, then
MPLS tunnel packets can be recongnized with packet
type 61 and 63.
It depends on pipeline personalization profile support
and changes of tunnel filter function.

This patch enables MPLS tunnel filter by replacing
inner_mac filter.
This configuration will be set when adding MPLSoUDP
and MPLSoGRE filter rules, and it will be invalid
only by NIC core reset.

Besides the typo, my previous comment about the title line still stands
("app/testpmd" is not accurate regarding the intent of this patch).

I didn't catch this during my previous review, naming it "label" is wrong
because users will actually specify the entire "label_tc_s_ttl" field at
once.
If you really want to name it "label" with the intent of only assigning the
initial 20b, have a look at ITEM_IPV6_TC and ITEM_IPV6_FLOW entries in the
same array.

Typo, "Lable". Also a minor comment, this word should be lower case since it
comes after a colon.

"Checksum" and "Protocol" should be lower case.
You must define a default mask as well.

This default mask is wrong, it has to be specified in network order (you can

Default mask is missing, you must add one.

OK, I see.
I think it's better to split this patch into two patches, one is for rte_flow, and the other is for testpmd, that'll be more clear.

I prefer having the new API stuff, documentation and testpmd implementation
at once especially since it's not a large patch, but it's your call.

Another note, you could use uint8_t[] to mitigate the endianness issue,
e.g.:
struct rte_flow_item_mpls {
/**
* Label (20b), TC (3b), Bottom of Stack (1b).
*/
uint8_t label_tc_s[3];
uint8_t ttl; /** Time-to-Live. */
};
/** Default mask for RTE_FLOW_ITEM_TYPE_MPLS. */
static const struct rte_flow_item_mpls rte_flow_item_mpls_mask = {
.label_tc_s = "\xff\xff\xf0",
};

This patchset adds support for MPLSoGRE and MPLSoUDP
tunnel filters.
I40e NICs can't recongnize MPLS tunnel packets by
default, so need to load a profile to FW first, then
MPLS tunnel packets can be recongnized with packet
type 61 and 63.
It depends on pipeline personalization profile support
and changes of tunnel filter function.
v3 changes:
Add big_buffer condition to this patchset.
Change some descriptions for new MPLS and GRE items.
Fix default mask error for MPLS label.

This patch enables MPLS tunnel filter by replacing
inner_mac filter.
This configuration will be set when adding MPLSoUDP
and MPLSoGRE filter rules, and it will be invalid
only by NIC core reset.

This patchset adds support for MPLSoGRE and MPLSoUDP
tunnel filters.
I40e NICs can't recongnize MPLS tunnel packets by
default, so need to load a profile to FW first, then
MPLS tunnel packets can be recongnized with packet
type 61 and 63.
It depends on pipeline personalization profile support
and changes of tunnel filter function.
v4 changes:
Move replace functions to i40e_ethdev.c.
v3 changes:
Add big_buffer condition to this patchset.
Change some descriptions for new MPLS and GRE items.
Fix default mask error for MPLS label.

MPLSoUDP & MPLSoGRE is not supported by tunnel
filter due to limited resource of HW, this patch
enables MPLS tunnel filter by replacing inner_mac
filter.
This configuration will be set when adding MPLSoUDP
and MPLSoGRE filter rules, and it will be invalid
only by NIC core reset.

Do you want to check if the mask is {00, 00, 00} or {FF, FF, F0}?
Why not just compare the mask with two constant array?
This function is difficult to understand.

You are checking (item->spec || item->mask) in all above cases.
Can we merge them to:
case RTE_FLOW_ITEM_TYPE_ETH:
case RTE_FLOW_ITEM_TYPE_IPV4:
case RTE_FLOW_ITEM_TYPE_IPV6:

Do we need replace every time when add each rule?

No, I will add a flag to distinguish it.

Yes, make sense, and actually we only care about {0xFF, 0xFF, 0xF0}. I will remove the function and judge it in parse function.

This patchset adds support for MPLSoGRE and MPLSoUDP
tunnel filters.
I40e NICs can't recongnize MPLS tunnel packets by
default, so need to load a profile to FW first, then
MPLS tunnel packets can be recongnized with packet
type 61 and 63.
It depends on pipeline personalization profile support
and changes of tunnel filter function.
v5 changes:
Rework MPLS parse function.
Add replace filter flag for MPLS.
v4 changes:
Move replace functions to i40e_ethdev.c.
v3 changes:
Add big_buffer condition to this patchset.
Change some descriptions for new MPLS and GRE items.
Fix default mask error for MPLS label.

MPLSoUDP & MPLSoGRE is not supported by tunnel
filter due to limited resource of HW, this patch
enables MPLS tunnel filter by replacing inner_mac
filter.
This configuration will be set when adding MPLSoUDP
and MPLSoGRE filter rules, and it will be invalid
only by NIC core reset.
