PCMCIA Test for Wireless

[Jo-Ellen F. Mathews]

Greetings,

First, I'd like to thank MontaVista, Magnus Damm and Embedded Planet for
all your wonderful help in getting modules and pcmcia card services
working on our RPX Lite 823.

We're still working on the port of our 11Mb wireless lan driver for Prism2
cards to the Power Mac and RPX platforms.  However, I've been using our
old 2Mb wireless driver to work out the module and pcmcia card services
issues I was experiencing.

Below is the beginning of the capture file (I'm using minicom) from the
RPX serial port when I ran a test.  The test results are the same
regardless of whether the wireless driver is compiled into the kernel or
loaded as a modules using pcmcia card services.

The test scenario is this:
* Station1 is a wireless station on the wireless network 192.168.151.0

* Station2 is a wired station on the wired network 192.168.100.0

* RPXLite823 is a station on both networks and routes the traffic
between the two networks.  Its root file system is mounted on wired
station 192.168.100.160.

We have a test script that repeatedly performs a 2MB ftp-get using wget.

I ran the test script simultaneously on both Station1 (ftp-get from
Station2) and Station2 (ftp-get from Station1) with RPXLite823 routing the
traffic between them.

The following partial capture shows some odd stuff I saw on the serial
port while the test was running up to the point where the ethernet
interface began failing.  Once the ethernet interface failed, the results
were the same for as long as the test ran with the occasional 'neighbour
table overflow' appearing.

The "exit" and "ping" commands appearing in the capture WERE NOT typed by
me or anyone else.  They were "automagically" pulled from the shell
history as the test was running.

Any comments on the strange serial behavior and why the ethernet interface
failed are welcome.  We're currently not too worried about all this for
this particular driver.  However, if the same behavior continues when we
complete the port of our 11Mb wireless driver to the RPX Lite 823, we'll
have a serious problem (ok, to be honest, we'll have an anxiety attack
;-).

Many thanks,
Jo-Ellen
