|
.Nm ef
|
|
.Nd "pseudo-device driver providing support for multiple Ethernet frame types"
|
|
.Sh SYNOPSIS
|
|
.Cd "device ef"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
pseudo-device driver clones each Ethernet type device with four
|
|
additional interfaces.
|
|
Each of them is capable to send or receive only
|
|
one predefined frame type.
|
|
.Pp
|
|
Names for the new interfaces are created by adding a
|
|
.Ar fN
|
|
suffix to an existing device name.
|
|
Where
|
|
.Ar N
|
|
is a device unit which can have one of the following values:
|
|
.Bd -literal -offset indent
|
|
0 interface with an Ethernet_II frame
|
|
1 interface with a Novell Ethernet_802.3 frame
|
|
2 interface with an Ethernet_802.2 frame
|
|
3 interface with an Ethernet_802.2/SNAP frame support.
|
|
.Ed
|
|
.Pp
|
|
For example, device
|
|
.Ar ed0
|
|
will be populated with four devices:
|
|
.Ar ed0f0 ,
|
|
.Ar ed0f1 ,
|
|
.Ar ed0f2
|
|
and
|
|
.Ar ed0f3 .
|
|
.Pp
|
|
After that, each device can be configured as usual:
|
|
.Dl # ifconfig ed0f1 ipx 0x105
|
|
This will configure IPX protocol with network number
|
|
.Ar 0x105
|
|
and
|
|
.Ar Ethernet_802.3
|
|
frame type.
|
|
.Pp
|
|
Please note that it is impossible to configure the IPX protocol on the parent
|
|
.Ar ed0
|
|
device after the
|
|
.Ar if_ef.ko
|
|
driver has been loaded.
|
|
.Pp
|
|
If the parent interface is not configured for any other protocol
|
|
(IP for example), subinterfaces will not function.
|
|
To avoid that, the parent interface should be
|
|
manually marked as
|
|
.Dq up :
|
|
.Dl # ifconfig ed0 up
|
|
.Sh EXAMPLES
|
|
The
|
|
.Nm
|
|
driver can be loaded via the
|
|
.Xr loader.conf 5
|
|
file:
|
|
.Dl if_ef_load="YES"
|
|
.Pp
|
|
In this case, ordinary interface configuration commands can be used
|
|
in the
|
|
.Xr rc.conf 5
|
|
file:
|
|
.Dl network_interfaces="ed2 lo0 tun0 ed2f0 ed2f1"
|
|
.Dl ifconfig_ed2f0_ipx="ipx 0x101"
|
|
.Dl ifconfig_ed2f1_ipx="ipx 0x102"
|
|
.Sh DIAGNOSTICS
|
|
None.
|
|
.Sh CAVEATS
|
|
Avoid to configure the parent Ethernet device for the IPX protocol, after the
|
|
.Nm
|
|
driver is loaded.
