Message-ID: <bug-1938-3@http.bugs.dpdk.org/> (raw)
http://bugs.dpdk.org/show_bug.cgi?id=1938
Bug ID: 1938
Summary: The NIC's imissed counter increments when the x710 VF
uses dpdk-l2fwd for data forwarding.
Product: DPDK
Version: 24.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: laitianli2000@163.com
Target Milestone: ---
With the i40e driver (v2.18.9, firmware 0x8000c407 1.3295.0) and DPDK
v24.11.5-rc1, aarch64 and ubuntu2204 system, when dpdk-l2fwd takes over the VF
for forwarding, injecting 500 Mbps of UDP traffic via pktgen results in an
incrementing imissed counter retrieved via rte_eth_stats_get().
