NAME
       oce -- Device driver for	Emulex OneConnect 10Gb network adapters

SYNOPSIS
       To  compile  this  driver into the kernel, place	the following lines in
       your kernel configuration file:

	     device pci
	     device oce

       Alternatively, to load the driver as a module at	boot time,  place  the
       following line in loader.conf(5):

	     if_oce_load="YES"

DEPRECATION NOTICE
       The oce driver may not be present in FreeBSD 15.0 and later.

DESCRIPTION
       Emulex  OneConnect  adapters  come  in various skews and	with different
       combinations of NIC, FCoE and iSCSI functions.  The oce	driver	claims
       the NIC functions in all	these adapters.

       The  oce	 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 Scal-
       ing (RSS) and MSI-X interrupts.

HARDWARE
       The oce driver supports the following network adapters:

       •   Emulex BladeEngine 2
       •   Emulex BladeEngine 3
       •   Emulex Lancer

UPDATING FIRMWARE
       Adapter firmware	updates	are persistent.

       Firmware	can be updated by following the	steps below:

       1.   Copy the below code	to a Makefile:

		  KMOD=elxflash
		  FIRMWS=imagename.ufi:elxflash
		  .include <bsd.kmod.mk>

       2.   Replace imagename in above with UFI	file name

       3.   Copy Makefile and UFI file to a directory

       4.   Execute make & copy	generated elxflash.ko to /lib/modules

       5.   sysctl dev.oce.<if_id>.fw_upgrade=elxflash

       6.   Reboot the machine

       In  case	 of  issues  with supplied UFI,	flashing fails with one	of the
       following errors.

       1.   "Invalid BE3 firmware image"
       2.   "Invalid Cookie. Firmware image corrupted ?"
       3.   "cmd to write to flash rom failed."
