I am assuming here that his problem is Mach not finding the device. 
If the problem is instead due to missing configuration, then this
current thread can be marked as spam and forgotten without any serious

There's a quick way to check whether Mach finds the device or not: to
run -- under the Hurd -- the command 'devprobe eth0'; if we don't get
'eth0' as output, then the eth0 device is not found by Mach.

So, if the problem is the Mach one, assuming that the card is
correctly working and rtl8139-compatible, the most probable thing
happening here is that its PCI ID is different from the ones listed in
the driver code.
In fact, every driver in the linux glue has a fixed list of PCI IDs
checked at driver initialization, and compatible devices are assumed
to be in the list.
Due to driver's code age, it may be possible that this card is newer
than driver, thus carrying an unlisted PCI ID -- and nobody ever used
the card with the hurd. Hence my interest on the output of 'lspci'. It
tells exactly the card model and vendor.
And 'lspci -n' tells you the proper PCI IDs, if we find that this is
the problem.

You had no problem on using RealTek card, since that was already listed.

Hope this clarifies.

It was a type of people I did not know, I found them very strange and
they did not inspire confidence at all. Later I learned that I had been
introduced to electronic engineers.
