LIQUIDIO(4) Kernel Interfaces Manual LIQUIDIO(4) NAME liquidio -- Cavium 10Gb/25Gb Ethernet driver SYNOPSIS To compile this driver into the kernel, place the following line in your kernel configuration file: device lio Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): if_lio_load="YES" DESCRIPTION The liquidio driver provides support for 23XX 10Gb/25Gb Ethernet adapters. The driver supports Jumbo Frames, Transmit/Receive checksum offload, TCP segmentation offload (TSO), Large Receive Offload (LRO), VLAN tag insertion/extraction, VLAN checksum offload, VLAN TSO, and Re- ceive 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 maxi- mum MTU size for Jumbo Frames is 16000. For more information on configuring this device, see ifconfig(8). HARDWARE The liquidio driver supports the following 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 SUPPORT For general information and support, go to the Cavium support website at: http://support.cavium.com.
