TMM crashes occur on the ingress side when using Mellanox CX5/CX6 NICs with the DPDK Mellanox MLX5 driver.
Traffic disrupted while tmm restarts.
The DPDK MLX5 driver causes a crash in TMM after it receives a packet that exceeds its MTU, followed by a stream of legitimate traffic (~30 MB). This issue only affects NICs that use the DPDK MLX5 driver, such as ConnectX-5 and ConnectX-6.
None
The MLX5 driver in the DPDK library has been fixed to correctly handle oversized packets.
