|
|
.Nd "Solarflare 10Gb Ethernet adapter driver"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device sfxge"
|
|
.Ed
|
|
.Pp
|
|
To load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
sfxge_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for 10Gb Ethernet adapters based on
|
|
Solarflare SFC9000 family controllers.
|
|
The driver supports jumbo
|
|
frames, transmit/receive checksum offload, TCP Segmentation Offload
|
|
(TSO), Large Receive Offload (LRO), VLAN checksum offload, VLAN TSO,
|
|
and Receive Side Scaling (RSS) using MSI-X interrupts.
|
|
.Pp
|
|
The driver allocates 1 receive queue, transmit queue, event queue and
|
|
IRQ per CPU up to a maximum of 64.
|
|
IRQ affinities should be spread out using
|
|
.Xr cpuset 1 .
|
|
Interrupt moderation may be controlled through the sysctl
|
|
.Va dev.sfxge.%d.int_mod
|
|
(units are microseconds).
|
|
.Pp
|
|
For more information on configuring this device, see
|
|
.Xr ifconfig 8 .
|
|
.Pp
|
|
A large number of MAC, PHY and data path statistics are available
|
|
under the sysctl
|
|
.Va dev.sfxge.%d.stats .
|
|
The adapter's VPD
|
|
fields including its serial number are available under the sysctl
|
|
.Va dev.sfxge.%d.vpd .
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver supports all 10Gb Ethernet adapters based on Solarflare SFC9000
|
|
family controllers.
