.Dd June 20, 1999 .Dt EF 4 .Os .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.
p 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: d -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
p For example, device .Ar ed0 will be populated with four devices: .Ar ed0f0 , .Ar ed0f1 , .Ar ed0f2 and .Ar ed0f3 .
p 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.
p 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"
p In this case an 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 configuring 'raw' ethernet device for IPX protocol after .Nm driver is loaded. .Sh SEE ALSO .Xr ipx 3 , .Xr ifconfig 8 .Sh AUTHORS .An Boris Popov Aq bp@freebsd.org .
