This patchset adds L2TPv2 protocol support to the ICE PMD
enabling RSS and Flow Director capabilities for L2TPv2 over UDP traffic.
v4: Version 3 patchset was incomplete due to a server reboot.
V4 includes all patches for review.
v3: Fixed compilation issues.
v2: Addressed AI generated comments.
Shaiq Wani (7):
net/ice: add L2TPv2 PPP and PPoE data structures
net/ice: add L2TPv2 tunnel type definition
net/ice: add L2TPv2 protocol and field definitions
net/ice: add L2TPv2 flow patterns and FDIR support
net/ice: add L2TPv2 hardware packet generation
net/ice: add L2TPv2 RSS hash support

This patchset adds L2TPv2 protocol support to the ICE PMD
enabling RSS and Flow Director capabilities for L2TPv2 over UDP traffic.
v5: Resending v4 patches with correct cover letter and threading.
v4: *Version 3 patchset was incomplete due to a server reboot.
*V4 includes all patches for review.
v3: Fixed compilation issues.
v2: Addressed AI generated comments.
Shaiq Wani (7):
net/ice: add L2TPv2 PPP and PPoE data structures
net/ice: add L2TPv2 tunnel type definition
net/ice: add L2TPv2 protocol and field definitions
net/ice: add L2TPv2 flow patterns and FDIR support
net/ice: add L2TPv2 hardware packet generation
net/ice: add L2TPv2 RSS hash support

## Review of DPDK Patch Series: L2TPv2 Support for net/ice
### Overall Summary
This is a 6-patch series adding L2TPv2 and PPP protocol support for Flow Director (FDIR) filtering in the Intel ice driver. The patches are generally well-structured, but there are several issues that need attention.
---
## Patch 1/6: net/ice: add L2TPv2 and PPP data structures
### Errors
None.
### Warnings
1. **Subject line could be more specific**: The subject mentions "L2TPv2 and PPP data structures" but the patch adds PPPoE structure (`ice_fdir_pppoe`) as well as PPP structure. Consider clarifying or keeping just PPP if PPPoE isn't used.
### Info
- The data structures are cleanly defined and follow existing patterns in the file.
---
## Patch 2/6: net/ice: add L2TPv2 tunnel type definition
### Errors
None.
### Warnings
None.
### Info
- Clean addition of the tunnel type enum and pattern structure fields.
---
## Patch 3/6: net/ice: add L2TPv2 protocol and field definitions
### Errors
None.
### Warnings
1. **Renaming existing macros may break compatibility**: This patch renames `ICE_PROT_MAC` to `ICE_PROT_MAC_OUTER`, `ICE_PROT_IPV4` to `ICE_PROT_IPV4_OUTER`, etc. If these macros are used anywhere outside this file, this could break compilation. Verify no external dependencies exist.
2. **Extra blank line at end of file**: There's a double blank line before the closing of the file (line after `ICE_INSET_TUN_IPV6_DST` definition).
### Info
- Good organization of inner/outer protocol definitions for tunnel support.
---
## Patch 4/6: net/ice: add L2TPv2 flow patterns and FDIR support
### Errors
1. **Inconsistent indentation in IPV6 handling block** (around lines 2213-2245): The code block for `RTE_FLOW_ITEM_TYPE_IPV6` has incorrect indentation. After the `p_v6` assignment, the `if (!(ipv6_spec && ipv6_mask))` block and subsequent code uses inconsistent indentation (mix of tabs and spaces not aligned properly). The closing sections starting from `if (!(ipv6_spec && ipv6_mask))` through `p_v6->hlim = ipv6_spec->hdr.hop_limits;` should be indented one level further to align with the case block.
2. **Multiple trailing blank lines at end of function** (line 2806): There are two extra blank lines before the closing of `ice_fdir_parse_pattern()`. Should be at most one.
3. **Missing variable declaration in block scope** (line 2590): `struct ice_fdir_l2tpv2 l2tpv2_be;` is declared in the middle of the switch case after other statements. In C89/C90 style (which DPDK sometimes follows for compatibility), declarations should be at the beginning of a block. This should be moved or the declaration should be in its own block.
### Warnings
1. **Inconsistent alignment in pattern table** (lines 160-176): The new L2TPv2 pattern entries have inconsistent tab alignment compared to the existing GTPU entries. While not breaking, it reduces readability.
2. **Long lines exceeding 100 characters**: Several lines in the L2TPv2 parsing section exceed 100 characters, for example:
- Line 2148: `if (tunnel_type && !is_outer && tunnel_type == ICE_FDIR_TUNNEL_TYPE_L2TPV2)`
- Multiple similar conditional lines in TCP/UDP handling
3. **Potential uninitialized variable**: `flags_version` is initialized to 0 on line 1899, but is used in flow type determination even when `l2tpv2_spec` might be NULL. The logic appears safe due to the `tunnel_type` check, but the flow is not immediately clear.
4. **Inconsistent spacing in conditionals**: Line 2809 has different indentation style:
```c
if (!input_set || filter->input_set_o &
~(item->input_set_mask_o | ICE_INSET_ETHERTYPE) ||
```
vs the original code alignment.
### Info
- The patch is large and implements comprehensive L2TPv2 FDIR support. Consider splitting into smaller patches if possible (e.g., pattern definitions separate from parsing logic).
---
## Patch 5/6: net/ice: add L2TPv2 hardware packet generation
### Errors
None.
### Warnings
None.
### Info
- Clean addition of case statements for the new L2TPv2 packet types.
---
## Patch 6/6: net/ice: add L2TPv2 RSS hash support
### Errors
None.
### Warnings
1. **Missing documentation update**: This patch adds new RSS types (`ICE_RSS_TYPE_IPV4_L2TPV2`, `ICE_RSS_TYPE_IPV6_L2TPV2`) but there's no corresponding documentation update for the new feature. Consider adding release notes for the L2TPv2 RSS support.
### Info
- The RSS hash configuration follows the existing pattern for other protocols.
---
## General Issues Across All Patches
### Warnings
1. **Missing release notes**: This feature series adds significant new functionality (L2TPv2 FDIR and RSS support) but no patch updates `doc/guides/rel_notes/`. A release notes entry should be added documenting the new L2TPv2 support.
2. **No test updates**: There are no corresponding test additions in `app/test` for the new L2TPv2 functionality.
### Info
- The series is well-organized with logical progression of changes.
- Each patch compiles independently based on the structure (data types → enums → definitions → implementation → hardware support → RSS).
- The Tested-by tags are present on all patches, indicating the code has been tested.

This patch has a lot of renaming going on and most of the changes are
renames unrelated (as far as I can see) to L2TP as described in the commit
log.
Please split this patch into two, with first patch doing all the renaming
of existing values. Then you can have a second patch that adds the new L2TP
parts.

This patchset adds L2TPv2 protocol support to the ICE PMD
enabling RSS and Flow Director capabilities for L2TPv2 over UDP traffic.
v6: split patch 3 into 2 seperate patches.
v5: Resending v4 patches with correct cover letter and threading.
v4: *Version 3 patchset was incomplete due to a server reboot.
*V4 includes all patches for review.
v3: Fixed compilation issues.
v2: Addressed AI generated comments.
Shaiq Wani (8):
net/ice: add L2TPv2 PPP and PPoE data structures
net/ice: add L2TPv2 tunnel type definition
net/ice: rename protocol identifiers
net/ice: add L2TPv2 protocol support
net/ice: add L2TPv2 flow patterns and FDIR support
net/ice: add L2TPv2 hardware packet generation
net/ice: add L2TPv2 RSS hash support

allowing flow classification and RSS hashing for L2TPv2 traffic.
v7: removed FDIR in doc and commit log titles.
v6: split patch 3 into 2 separate patches.
v5: Resending v4 patches with correct cover letter and threading.
v4: *Version 3 patchset was incomplete due to a server reboot.
*V4 includes all patches for review.
v3: Fixed compilation issues.
v2: Addressed AI generated comments.
*** BLURB HERE ***
Shaiq Wani (7):
net/ice: add L2TPv2 PPP and PPoE data structures
net/ice: add L2TPv2 tunnel type definition
net/ice: rename protocol identifiers
net/ice: add L2TPv2 protocol support
net/ice: add L2TPv2 flow pattern matching support
net/ice: add L2TPv2 hardware packet generation
net/ice: add L2TPv2 RSS hash support
