awi driver & Zoom Air 4000

["Ian Cass" <ian.cass@knowledge.com>]

Hi,

I picked up some dirt cheap PCMCIA ZoomAir 4000 802.11 2meg wireless
ethernet cards recently & am seeing if I can get them to work with OBSD.
They are based on the PRISM1 wireless chipset from Harris & the AMD
PCnetMobile chipset. There exists a driver for this chipset within OpenBSD
and NetBSD (awi driver).

I've added the PCMCIA CIS vendor strings to the driver and have it
successfully matching the card & attaching the driver. It finds the
appropriate memory space, recognises the card as a an IEEE802.11 DS 2Mbps
card with PCnetMobile v2:01 firmware and appears to work OK.

If I ifconfig the card in adhoc mode, it finds the SSID of my wireless LAN
(without me having to specify it!!). On my other machine - a Windows ME box,
the driver indicates the cards are linked and see's the MAC address of the
other card. Ethernet Conversion mode on the Windows box is 'Encapsulated'
but I have options for 802.1h and RFC1042 (neither of which work any better.
>From reading the OBSD driver source code, it seems to simply encapsulate the
packets.

The OBSD box is set up on 192.168.0.2/255.255.255.0 and the windows box on
192.168.0.1/255.255.255.0.

If I ping the Windows box from the OBSD box, it tells me the host is down -
then changes to 'No buffer space available' once the drivers send buffer
fills. This seems to suggest to me it's having bother sending anything.

If I ping the OBSD box from windows, it also reports that the host is down
(as you'd expect). However, if I run a tcp dump on awi0 on the OBSD box, I
see 'arp who-has 192.168.0.2 tell 192.168.0.1'.  I also see some NetBIOS
broadcast traffic and some broadcast udp. Interestingly enough, if I run
dhclient on the BSD box, I see bootp broadcast traffic coming back. All the
time though, I get 'No buffer space available' messages.

Looks very much like it can receive data but not send, for some reason.

I guess next step is to run OBSD on the server (the Windows box) as well and
tcpdump to see if it's receiving anything from the client.

Is there anyone who has experimented with using Zoom Air 4000 2meg cards on
OBSD? Anyone else who's using the awi driver with other cards who can share
any information?

dmesg attached below
