Accelerated packet capture and trasmission for Intel adapters is available on PF_RING ZC by means of specialised drivers as described in the PF_RING ZC section. Please also read Installing from packages for installation and configuration instructions.
3.1. Supported Intel NICs Comparison¶
This table below helps you understanding what features are delivered by each Intel driver family and chipset model.
|Max Port Speed (Gbit)||1||1||10||10||40||40||100||100|
|Symmetric RSS||No RSS||Yes||Yes||Yes||Dep on Fw||Dep on Fw||Yes||Yes|
|RX Hardware Timestamp||82580/i350||Yes|
|Read/Set Device Clock||Yes|
|Dual mode (Kernel and ZC)||Yes||Yes||Yes||Yes||Yes||Yes||Yes|
- Symmetric RSS: on some adapters (e.g. i40e) this depends on the firmware version, a message is dmesg is printed to warn about this when no symmetric support is detected.
- Dual mode: ZC drivers supporting this mode can run as standard kernel drivers when there is no ZC socket running for the specific interface.
