Subject: [dpdk-dev] net/mlx5: rte_flow_item_gtp restricted to GTPU

Hi everybody,


I've implemented some flows offloading through rte_flow, and I'm just 
finding out that my GTPC packets aren't handled the same way as my GTPU 
ones by a Mellanox Connect-X6(FLEX_PARSER_PROFILE_ENABLE==3).

In others words, the GTP rules that I set are ignoring GTPC packets. The 
DPDK api doc doesn't say anything about any GTP-C/GTP-U distinction as 
far as I know, only that there's no way to set some filter against a 
GTPv2(GTP-C) header.

There's a reference to RTE_GTPU_UDP_PORT in 
dpdk.20.11.2/drivers/net/mlx5/mlx5_flow_dv.c::flow_dv_translate_item_gtp(), 
and none to RTE_GTPC_UDP_PORT.

Do you confirm that mlx5 rte_flow implementation is definitely ignoring 
GTPC packets? And, if so, for which reason?


Thanks a lot.


Regards.
