[dpdk-users] Enabling Hardware vlan filtering fore received VLAN packets in DPDK causes performance issues

[Suchetha p]

Hi,

To enable hardware filtering by an Ethernet device of received VLAN packets
tagged with a given VLAN Tag Identifier - DPDK API rte_eth_dev_vlan_filter
is being used.Vlan filtering enabled to support multiple VLAN allocation
per VF Invoking this API for every received VLAN packet is causing some
performance issues like CPU overload  - 100% and packet forwarding
delays.Is this a known issue?We are using DPDK version 18.08 and OS version
RHEL 7.6.
Please suggest how to overcome this issue?



Thanks,
Suchetha
