LIQUIDIO(4)		 BSD Kernel Interfaces Manual		   LIQUIDIO(4)

NAME
     liquidio -- Cavium	10Gb/25Gb Ethernet driver for the FreeBSD operating
     system

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.  Se-
     lecting an	MTU larger than	1500 bytes with	the ifconfig(8)	utility	con-
     figures 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 the following	cards:

     +o	 LiquidIO II CN2350 210SV/225SV
     +o	 LiquidIO II CN2360 210SV/225SV

LOADER TUBABLES
     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
