Bug ID: 1112
Summary: MLX5: Not able to configure flows on PPPoE, stacked
vlan tunnels & enable multiple tunnels at a time
Product: DPDK
Version: 22.03
Hardware: All
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: core

Hello Team,

We need to distribute packets on Inner-Hash5Tuple (IP-IP-Port-Port-Protocol) on Rx queues of below mentioned packet hierarchies.
we're using rte_flow to create rules on group 0 with action RSS.

Packet hierarchy:
Case 1:
ETH->VLAN1_QinQ->VLAN2_QinQ->VLAN3_QinQ->VLAN4_QinQ->PPPoE->PPP->IPv4/v6->TCP/UDP.

We tried following:
1. If we configure flow rte_flow_item pattern as ETH->VLAN->VLAN, API throws error for multiple VLANs
2. If we configure ETH->ANY->PPPoES->.., API throws "item not supported"

Please suggest way to support the hierarchy.

Secondly,
we want to enable GTP, IPinIP & other tunnels at same time, to enable GTP, mlx5 has configure to FLEX_PARSER_PROFILE_ENABLE=3 & to other value to support another.

Card Model: Connectx-6 Dx
OS: Ubuntu 20.04
Firmware: 22.32.2004
