.Dd February 8, 2012 .Dt SFXGE 4 .Os .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: d -ragged -offset indent .Cd "device sfxge" .Ed
p To load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -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.
p 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).
p For more information on configuring this device, see .Xr ifconfig 8 .
p 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. .Sh SUPPORT For general information and support, go to the Solarflare support website at:
