* The following #define causes the code to use PIO to access the
* chip's registers instead of memory mapped mode. The reason PIO mode
* is on by default is that the Etherlink XL manual seems to indicate
* that only the newer revision chips (3c905B) support both PIO and
* memory mapped access. Since we want to be compatible with the older
* bus master chips, we use PIO here. If you comment this out, the
* driver will use memory mapped I/O, which may be faster but which
* might not work on some devices.
