How to configure an ethernet dev as PtP ?

Hello all,

I tried to configure an ethernet device as a pointopoint link recently, just to
find out that this does not work as one would expect via:

ifconfig eth0 192.168.1.1 pointopoint 192.168.5.1 up

I tried on kernel 2.4.21-pre6 and 2.2.19 (just to name two), both the same. It
comes up as:

eth0 Link encap:Ethernet HWaddr 00:04:76:F7:E9:17
inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST MULTICAST MTU:1500 Metric:1

I do not understand why this does not work out just like another ptp-interface
like isdn:

isdn0 Link encap:Ethernet HWaddr FC:FC:00:00:00:00
inet addr:192.168.1.1 P-t-P:192.168.5.1 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MTU:1500 Metric:1

Is there anything I mis-understood or a good reason for not being able to make
eth pointopoint?

I have the feeling this question is pretty brain-dead, but anyway, maybe some
kind soul can drop a few words ...
