+.Sh NAME
+.Nm ef
+.Nd
+pseudo-device driver provides support for multiple ethernet frame types.
+.Sh SYNOPSIS
+.Cd "kldload if_ef.ko"
+.Sh DESCRIPTION
+The 
+.Nm
+pseudo-device driver clones each ethernet type device with four
+additional interfaces. Each of them capable to send or receive only
+one predefined frame type.
+.Pp
+Names for the new interfaces created by adding
+.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 usually:
+.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 IPX protocol on the 'raw'
+.Ar ed0
+device after
+.Ar if_ef.ko
+driver loaded.
+.Sh EXAMPLES
+The
+.Nm
+driver can be loaded via
+.Xr loader.conf 5
+file:
+.Dl if_ef_load="YES"
+.Pp
+In this case an ordinary interface configuration commands can be used
+in
+.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 configuring 'raw' ethernet device for IPX protocol after
+.Nm
+driver is loaded.

+.Xr ifconfig 8
