38 .Nd "Cavium 10Gb/25Gb Ethernet driver for the FreeBSD operating system"
40 To compile this driver into the kernel,
41 place the following line in your
42 kernel configuration file:
43 .Bd -ragged -offset indent
47 Alternatively, to load the driver as a
48 module at boot time, place the following line in
50 .Bd -literal -offset indent
56 driver provides support for 23XX 10Gb/25Gb Ethernet adapters.
57 The driver supports Jumbo Frames, Transmit/Receive checksum
58 offload, TCP segmentation offload (TSO), Large Receive Offload (LRO),
59 VLAN tag insertion/extraction, VLAN checksum offload,
60 VLAN TSO, and Receive Side Steering (RSS)
62 Support for Jumbo Frames is provided via the interface MTU setting.
63 Selecting an MTU larger than 1500 bytes with the
65 utility configures the adapter to receive and transmit Jumbo Frames.
66 The maximum MTU size for Jumbo Frames is 16000.
68 For more information on configuring this device, see ifconfig(8).
72 driver supports the following cards:
76 LiquidIO II CN2350 210SV/225SV
78 LiquidIO II CN2360 210SV/225SV
81 Tunables can be set at the
83 prompt before booting the kernel or stored in
86 .Bl -tag -width indent
89 String that specifies type of firmware to be loaded.
90 Default is "nic". Use "none" to load firmware from flash.
91 .It Va hw.lio.num_queues_per_pf0
93 Unsigned integers that specify number of queues per PF0.
94 Valid range is 0 to 64.
95 Use 0 to derive autoconfigures based on the number of
97 .It Va hw.lio.num_queues_per_pf1
99 Unsigned integers that specify number of queues per PF1.
100 Valid range is 0 to 64.
101 Use 0 to derive autoconfigures based on the number of
103 .It Va hw.lio.console_bitmask
105 Bitmask indicating which consoles have debug output
106 redirected to syslog.
109 To enable/disable driver RSS support
112 To enable/disable hardware LRO
