.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:
.Bd -ragged -offset indent
.Cd "device pci"
.Cd "device oce"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent
if_oce_load="YES"
.Ed

.Sh UPDATING FIRMWARE
Adapter firmware updates are persistent.
.Pp
Firmware can be updated by following the steps below:
.Bl -enum
.It
Copy the below code to a Makefile:
.Bd -literal -offset indent
KMOD=elxflash
FIRMWS=imagename.ufi:elxflash
\&.include <bsd.kmod.mk>
.Ed
.It
Replace imagename in above with UFI file name
.It
Copy Makefile and UFI file to a directory
.It
Execute make & copy generated elxflash.ko to
.Pa /lib/modules
.It
sysctl dev.oce.<if_id>.fw_upgrade=elxflash
