Removing ARCNET stuffs

[Frank Wille]

My current status is that the A4000 is running again (in AGA), after I
removed the graphics card. The A3000 still needs a rework of the PSU.

Done! Replacing the capacitors in the PSU fixed it. And I got two A2060
ARCnet cards and a cable last weekend.

The A2060 is recognized by the 7.0 kernel:

bah0 at zbus0 pa 0xea0000 man/pro 514/9: link addr 0x75(117)

ifconfig(8) shows:

bah0: flags=8a22<BROADCAST,NOTRAILERS,ALLMULTI,SIMPLEX,MULTICAST> mtu 507
address: 75

But how do I configure an ARCnet network? Can I use "inet"? I tried this
without succuess:

# ifconfig bah0 10.0.0.1 up
ifconfig: SIOCAIFADDR: Inappropriate ioctl for device

And ifconfig(8) looks strange after that (double bah0: output?):

bah0: flags=8e63<UP,BROADCAST,NOTRAILERS,RUNNING,ALLMULTI,OACTIVE>bah0:
flags=8e63<SIMPLEX,MULTICAST> mtu 507
address: 75

Yes, inet and inet6 should work.

IP over ARCnet has two modes. An old protocol works without ARP, it
requires that the 8bit-MAC address is the same as the last IP octet.
The MAC-address of an A2060 is configured with DIP-switches.

With ARP, there is an arbitary mapping. This new protocol also allows
larger MTUs by splitting the IP datagram into smaller ARCnet packets.
This is a kind of fragmentation below the IP level.


The ioctl message however looks more like the driver is broken.
