New Revision: 227569
URL: http://svn.freebsd.org/changeset/base/227569
Log:
Add the sfxge(4) device driver, providing 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.
This work was sponsored by Solarflare Communications, Inc.
My sincere thanks to Ben Hutchings for doing a lot of the hard work!

+.Sh NAME
+.Nm sfxge
+.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 8 .
+Interrupt moderation may be controlled through the sysctl
+dev.sfxge.\fIindex\fR.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 dev.sfxge.\fIindex\fR.stats. The adapter's VPD
+fields including its serial number are available under the sysctl
+dev.sfxge.\fIindex\fR.vpd.
+.Sh HARDWARE
+The
+.Nm
+driver supports all 10Gb Ethernet adapters based on Solarflare SFC9000
+family controllers.
+.Sh SUPPORT
+For general information and support,
+go to the Solarflare support website at:
+.Pa https://support.solarflare.com .
+.Sh SEE ALSO
+.Xr arp 4 ,
+.Xr netintro 4 ,
+.Xr ng_ether 4 ,
+.Xr vlan 4 ,
+.Xr cpuset 8 ,
+.Xr ifconfig 8
+.Sh AUTHORS
+The
+.Nm
+driver was written by
+.An Philip Paeps
+and
