33 .Nd "pseudo-device driver providing support for multiple Ethernet frame types"
39 pseudo-device driver clones each Ethernet type device with four
40 additional interfaces.
41 Each of them is capable to send or receive only
42 one predefined frame type.
44 Names for the new interfaces are created by adding a
46 suffix to an existing device name.
49 is a device unit which can have one of the following values:
50 .Bd -literal -offset indent
51 0 interface with an Ethernet_II frame
52 1 interface with a Novell Ethernet_802.3 frame
53 2 interface with an Ethernet_802.2 frame
54 3 interface with an Ethernet_802.2/SNAP frame support.
59 will be populated with four devices:
66 After that, each device can be configured as usual:
67 .Dl # ifconfig ed0f1 ipx 0x105
68 This will configure IPX protocol with network number
74 Please note that it is impossible to configure the IPX protocol on the parent
78 driver has been loaded.
80 If the parent interface is not configured for any other protocol
81 (IP for example), subinterfaces will not function.
82 To avoid that, the parent interface should be
