Opened: Sep 24, 2024 Severity: 2-Critical
The data plane interface of TMM receives packets that are larger than the Maximum Transmission Size (MTU) set on the Virtual Function (VF) (see the "max_sz" column by running the command "tmctl -d blade -w 250 tmm/ndal_rx_stats"). The configured MTU can be seen through the "tmctl -d blade -w 250 tmm/ndal_dev_status" table.
TMM stops processing traffic.
SPK is deployed with: - Mellanox CX-5 NIC. - The MTU configured on the data plane interface is less than the MTU configured on the switch port that is directly connected to the Network Interface Card (NIC).
None
The DPDK mlx5 driver now correctly handles non-critical error packets, preventing traffic disruption.
