Hi,
I have the same trouble with the DFE-690 from D-link.
I tried to install the drivers as described by the shipped files on the installation CD-rom (Linux directory), without success.
I downloaded the cardbus package (cardbus_DFE-690TXD.tar.gz with rtl8139.c) from John Lapeyre's website at http://personal.riverusers.com/~lapeyre/.
I also tried to install the driver_ops.h file, as it seems this file is not present on any of my systems (linux mandrake 8.1, 9.1, Debian Woody).
Even the package pcmcia-cs-3.2.7.tar.gz doesn't help.
I browsed the scyld pages as well.
At compile time of the rtl8139.c file with the required options, the list of errors is too long to list here.
What can be done?
Mathias.
