💖 LIQUIDIO(4) from the Kernel Interfaces Manual — Cavium 10Gb/25Gb Ethernet driver 💖

Okay bestie, gather round — this is the whole liquidio vibe, no cap, every detail intact. 🫶

🌸 NAME 🌸

liquidio — Cavium 10Gb/25Gb Ethernet driver.

✨ SYNOPSIS ✨

To compile this driver into the kernel, place this line in your kernel configuration file:

device lio

Alternatively, to load the driver as a module at boot time, place this line in loader.conf(5):

if_lio_load="YES"

🦋 DESCRIPTION 🦋

The liquidio driver provides support for 23XX 10Gb/25Gb Ethernet adapters. It’s giving the full feature lineup: Jumbo Frames, Transmit/Receive checksum offload, TCP segmentation offload (TSO), Large Receive Offload (LRO), VLAN tag insertion/extraction, VLAN checksum offload, VLAN TSO, and Receive Side Steering (RSS).

Support for Jumbo Frames is provided via the interface MTU setting. Selecting an MTU larger than 1500 bytes with the ifconfig(8) utility configures the adapter to receive and transmit Jumbo Frames. The maximum MTU size for Jumbo Frames is 16000.

For more information on configuring this device, see ifconfig(8).

🎀 HARDWARE 🎀

The liquidio driver supports these cards:

  • LiquidIO II CN2350 210SV/225SV
  • LiquidIO II CN2360 210SV/225SV

💅 LOADER TUNABLES 💅

Tunables can be set at the loader(8) prompt before booting the kernel, or stored in loader.conf(5).

  • hw.lio.fw_type — String that specifies type of firmware to be loaded. Default is "nic". Use "none" to load firmware from flash.
  • hw.lio.num_queues_per_pf0 — Unsigned integers that specify number of queues per PF0. Valid range is 0 to 64. Use 0 to derive autoconfigures based on the number of cpus with a max of 8.
  • hw.lio.num_queues_per_pf1 — Unsigned integers that specify number of queues per PF1. Valid range is 0 to 64. Use 0 to derive autoconfigures based on the number of cpus with a max of 8.
  • hw.lio.console_bitmask — Bitmask indicating which consoles have debug output redirected to syslog.
  • hw.lio.rss — To enable/disable driver RSS support.
  • hw.lio.hwlro — To enable/disable hardware LRO.
