.Dd February 19, 2012 .Dt OCE 4 .Os .Sh NAME .Nm oce .Nd "Device driver for Emulex OneConnect 10Gb network adapters" .Sh SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "device pci" .Cd "device oce" .Ed
p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent if_oce_load="YES" .Ed .Sh DESCRIPTION Emulex OneConnect adapters come in various skews and with different combinations of NIC, FCoE and iSCSI functions. The .Nm driver claims the NIC functions in all these adapters.
p The .Nm driver supports VLAN Hardware offload, TCP checksum offload, TCP segmentation offload (TSO), Large receive offload (LRO), Bonding, Jumbo frames (from 1500 - 9000), Multiple TX queues, Receive-Side Scaling (RSS) and MSI-X interrupts. .Sh HARDWARE The .Nm driver supports the following network adapters:
p l -bullet -compact t Emulex BladeEngine 2 t Emulex BladeEngine 3 t Emulex Lancer .El .Sh UPDATING FIRMWARE Adapter firmware updates are persistent.
p Firmware can be updated by following the steps below: l -enum t Copy the below code to a Makefile:
p d -literal -offset indent .KMOD=elxflash FIRMWS=imagename.ufi:elxflash .include <bsd.kmod.mk> .Ed t Replace imagename in above with UFI file name t Copy Makefile and UFI file to a directory t Execute make & copy generated elxflash.ko to
a /lib/modules t sysctl dev.oce.<if_id>.fw_upgrade=elxflash t Reboot the machine .El
p In case of issues with supplied UFI, flashing fails with one of the following errors.
p l -enum -compact t .Qq Invalid BE3 firmware image t .Qq "Invalid Cookie. Firmware image corrupted ?" t .Qq cmd to write to flash rom failed. .El .Sh SUPPORT For general information and support, go to the Emulex website at:
