mlx5: vlan/qinq packets are not matched by eth/ipv4 RTE_FLOW

Bug ID: 535
Summary: mlx5: vlan/qinq packets are not matched by eth/ipv4
RTE_FLOW
Product: DPDK
Version: 19.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: ethdev
Assignee: [email protected]
Reporter: [email protected]Target Milestone: ---
With dpdk 19.11.0, the following rte_flow created in test pmd:
Quoted 1 line
flow create 0 ingress pattern eth type spec 0 type mask 0 / ipv4 / end
actions mark id 2 / queue index 0 / end
was able to match ipv4 whatever if the packets has 0 or N vlan headers. With dpdk 19.11.4, it's not anymore possible.
Only packets without vlan header are matched. It means that packet having the type field in the ethernet header not equal to 0x800 are not matched. But in the RTE_FLOW, the mask of the type field of the Ethernet item is set to 0.
By the way, I can also reproduce the issue with the master branch.
