dpservice fails to start when compiling with DPDK 24.11.2

[byteocean]

dpservice is updated to be compatible with DPDK 24.11.1 and it can start in the normal mode without an issue. But using DPDK 24.11.2 (discovered accidentally) seems to block the starting process of dpservice with following error message:

2025-05-06 10:41:20.094 1(control) I SERVICE: Init isolation flow rules [../src/dp_port.c:430:dp_port_install_sync_isolated_mode()]
2025-05-06 10:41:20.094 1(control) E SERVICE: Flow cannot be validated, port_id: 0, flow_error: multiple tunnel not supported, error: -22, errmsg: Invalid argument [../src/rte_flow/dp_rte_flow.c:115:dp_install_rte_flow()]
2025-05-06 10:41:20.094 1(control) I SERVICE: Stopping port, port_id: 0, socket_id: 0 [../src/dp_port.c:388:dp_stop_eth_port()]

By checking the result of applying patches, the function pattern_template_validate is already skipped as it should be. Thus, further investigation is needed to resolve this error.

We no longer use SYNC flows nor the original eswitch and only use ASYNC + multiport-eswitch in OSC.

I do have a secondary local machine with that config however and was able to confirm this for non-multiport config.

It is caused by this commit.

This is again looking like a verification that is more strict than the actual card, hence I would suggest to simply revert the patch. However I was unable to do proper testing with traffic due to the above facts.

If you can verify that reverting it works fine, then a short reversal patch like the dpdk_24_11_mtu.patch can be created.
