[PATCH v10 12/20] net/sxe2: add support for custom UDP tunnel ports

liujie5 at linkdatatechnology.com liujie5 at linkdatatechnology.com
Sat Jun 6 03:07:18 CEST 2026


From: Jie Liu <liujie5 at linkdatatechnology.com>

This patch enables the configuration of custom UDP port numbers for
tunneling protocols in the SXE2 PMD.

The change includes:
- Adding a new entry in the tunnel port lookup table.
- Updating the hardware profile to recognize
  the custom UDP port as a tunnel type.
- Enabling inner header parsing for packets arriving on these ports.

This allows the Switch module to correctly apply recipes based on
inner packet fields (e.g., inner MAC or IP).
