Bring in the Broadcom/Emulex Fibre Channel driver, ocs_fc(4).

Browse source 
The ocs_fc(4) driver supports the following hardware:

Emulex 16/8G FC GEN 5 HBAS
	LPe15004 FC Host Bus Adapters
	LPe160XX FC Host Bus Adapters

Emulex 32/16G FC GEN 6 HBAS
	LPe3100X FC Host Bus Adapters
	LPe3200X FC Host Bus Adapters

The driver supports target and initiator mode, and also supports FC-Tape.

Note that the driver only currently works on little endian platforms.  It
is only included in the module build for amd64 and i386, and in GENERIC
on amd64 only.

.Sh NAME
.Nm ocs_fc
.Nd "Device driver for Emulex Fibre Channel Host Adapters"
.Sh SYNOPSIS
To compile this driver into the kernel, add this line to the
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device ocs_fc"
.Ed
.Pp
To load the driver as a module at boot, add this line to
.Xr loader.conf 5 :
.Bd -literal -offset indent
ocs_fc_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver provides access to Fibre Channel SCSI devices.
.Pp
The
.Nm
driver supports initiator and target modes.
Support is available for Arbitrated loops, Point-to-Point,
and Fabric connections.
FC-Tape is highly recommended for connections to tape drives that support
it.
FC-Tape includes four elements from the T-10 FCP-4 specification:
.Bl -bullet -offset indent
.It
Precise Delivery of Commands
.It
Confirmed Completion of FCP I/O Operations
.It
Retransmission of Unsuccessfully Transmitted IUs
.It
Task Retry Identification
.El
.Pp
Together these features allow for link level error recovery with tape
devices.
Without link level error recovery, an initiator cannot, for instance, tell whether a tape write
command that has timed out resulted in all, part, or none of the data going to
the tape drive.
FC-Tape is automatically enabled when both the controller and target support it.
.Sh HARDWARE
The
.Nm
driver supports these Fibre Channel adapters:
.Bl -tag -width xxxxxx -offset indent
.It Emulex 16/8G FC GEN 5 HBAS
.Bd -literal -offset indent
LPe15004 FC Host Bus Adapters
LPe160XX FC Host Bus Adapters
.Ed
.It Emulex 32/16G FC GEN 6 HBAS
.Bd -literal -offset indent
LPe3100X FC Host Bus Adapters
LPe3200X FC Host Bus Adapters
.Ed
.El
.Sh UPDATING FIRMWARE
Adapter firmware updates are persistent.
.Pp
Firmware can be updated by following these steps:
.Bl -enum
.It
Copy this code to a
.Pa Makefile :
.Bd -literal -offset indent
KMOD=ocsflash
FIRMWS=imagename.grp:ocsflash
\&.include <bsd.kmod.mk>
.Ed
.It
Replace
.Pa imagename
with the name of the GRP file.
.It
Copy the
.Pa Makefile
and GRP file to a local directory
.It
Execute
.Cm make
and copy the generated
.Pa ocsflash.ko
file to
.Pa /lib/modules
.It
.Cm sysctl dev.ocs_fc.<N>.fw_upgrade=ocsflash
.It
Check kernel messages regarding status of the operation
.It
Reboot the machine
.El
.Pp
.Sh BOOT OPTIONS
Options are controlled by setting values in
.Pa /boot/device.hints .
.Pp

* then it grabs each IO object within the slab and adds it to the free list.
* Individual command, response and SGL DMA buffers are allocated for each IO.
