Subject: [dpdk-users] Enabling Hardware vlan filtering fore received VLAN packets in DPDK causes performance issues
Date: Sat, 14 Sep 2019 15:57:12 +0530 [thread overview]
Message-ID: <CAOGjjAOgb0uU67+Zx2CW7yFiR1mO0vCus7mViGYnEujw84NTJg@mail.gmail.com> (raw)
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
