30.Sh NAME
31.Nm sfxge
32.Nd "Solarflare 10Gb Ethernet adapter driver"
33.Sh SYNOPSIS
34To compile this driver into the kernel,
35place the following lines in your
36kernel configuration file:
37.Bd -ragged -offset indent
38.Cd "device sfxge"
39.Ed
40.Pp
41To load the driver as a
42module at boot time, place the following line in
43.Xr loader.conf 5 :
44.Bd -literal -offset indent
45sfxge_load="YES"
46.Ed
47.Sh DESCRIPTION
48The
49.Nm
50driver provides support for 10Gb Ethernet adapters based on
51Solarflare SFC9000 family controllers.
52The driver supports jumbo
53frames, transmit/receive checksum offload, TCP Segmentation Offload
54(TSO), Large Receive Offload (LRO), VLAN checksum offload, VLAN TSO,
55and Receive Side Scaling (RSS) using MSI-X interrupts.
56.Pp
57The driver allocates 1 receive queue, transmit queue, event queue and
58IRQ per CPU up to a maximum of 64.
59IRQ affinities should be spread out using
60.Xr cpuset 1 .
61Interrupt moderation may be controlled through the sysctl
62.Va dev.sfxge.%d.int_mod
63(units are microseconds).
64.Pp
65For more information on configuring this device, see
66.Xr ifconfig 8 .
67.Pp
68A large number of MAC, PHY and data path statistics are available
69under the sysctl
70.Va dev.sfxge.%d.stats .
71The adapter's VPD
72fields including its serial number are available under the sysctl
73.Va dev.sfxge.%d.vpd .
74.Sh HARDWARE
75The
76.Nm
77driver supports all 10Gb Ethernet adapters based on Solarflare SFC9000
78family controllers.
