|
.Nm enic
|
|
.Nd "VIC Ethernet NIC driver"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device iflib"
|
|
.Cd "device enic"
|
|
.Ed
|
|
.Pp
|
|
To load the driver as a module at run-time,
|
|
run the following command as root:
|
|
.Bd -literal -offset indent
|
|
kldload if_enic
|
|
.Ed
|
|
.Pp
|
|
To load the driver as a
|
|
module at boot time, place the following lines in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
if_enic_load="YES"
|

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for Cisco Virtual Interface Card.
|
|
Support is limited to basic network connectivity.
|
|
Media is controlled by the NIC itself since there can be multiple
|
|
virtual PCI NIC devices exposed to the PCI bus.
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver should supports all known Cisco VIC cards.
|
|
.Sh CONFIGURATION
|
|
The
|
|
.Nm
|
|
network interface is configured using
|
|
.Xr ifconfig 8
|
|
and the
|
|
.Xr sysctl 8
|
|
tree at
|
|
.Dv dev.enic.<N> .
|
|
All configurable entries are also tunables, and can be put directly into the
|
|
.Xr loader.conf 5
|
|
for persistent configuration.

|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
device driver first appeared in
