Flow API, including Flow isolated mode.

RSS hash result is supported. Statistics query including Basic, Extended and per queue.
Limitations For secondary process: Forked secondary process not supported. If the external memory is registered by primary process but has different virtual address in secondary process, unexpected error may happen.
Flow pattern without any specific vlan will match for vlan packets as well: Meaning, the flow rule: Will match any ipv4 packet VLAN included. A multi segment packet must have less than 6 segments in case the Tx burst function is set to multi-packet send or Enhanced multi-packet send.
Otherwise it must have less than 50 segments. Note MAC addresses not already present in the bridge table of the associated kernel network device will be added and cleaned up by the PMD when closing the device.

Mellanox MCX414A-BCAT Network Card case of ungraceful program termination, some entries may remain present and should be removed manually by other means. As the mempool for the external buffer is managed by PMD, all the Rx mbufs must be freed before the device is closed. Otherwise, the mempool of the external buffers will be freed by PMD and the application which still holds the external buffers may be corrupted.
IPv6 Multicast messages are not supported on VM, while promiscuous mode and allmulticast mode are both set to off.

Statistics MLX5 supports various of methods to report statistics: The received and sent statistics are through SW only and counts the number of packets received or sent successfully by the PMD. The imissed counter is the amount of packets Mellanox MCX414A-BCAT Network Card could not be delivered to SW because a queue was full. The extended statistics expose a wider set of counters counted by the device. The extended port statistics counts the number of packets received or sent successfully by the port.
The flow counter counts the number of packets received successfully by the port and match the specific flow. Configuration These options can be modified in the. This option has no performance impact.
Enabling this option adds additional run-time checks and debugging messages at the cost of lower performance. Note For Bluefield, target should be set to armbluefield-linux-gcc. Default armv8a configuration of make build Mellanox MCX414A-BCAT Network Card meson build set it to then brings performance degradation.
By default, the HW Tx doorbell is configured as a write-combining Mellanox MCX414A-BCAT Network Card. The register would be flushed to HW usually when the write-combining buffer becomes full, but it depends on CPU design.

Except for vectorized Tx burst routines, a write memory barrier is enforced after updating the register so that the update can be immediately visible to HW. However, setting this environmental variable will bring better latency even though the maximum throughput can slightly Mellanox MCX414A-BCAT Network Card. Forcing them down prevents packets reception.
This feature allows to save PCI bandwidth and improve performance. The size of CQE is aligned with the size of a cacheline of the core.
