* Fortunately the code that enables and disables the multiple
* fuctions of the card won't mess with the lower bit for cards
* that aren't stanards conforming MFC cards (which these olicom
* cards aren't).
*
* Note: These cards still don't get interrupts for reasons
* unknown, even when the right cfe is selected. There's likely
* something in the CCR that needs to be manually tweaked, but
* the COR bits seem to all be used. Bit 0 and 3 are always set
* and the other bits select the config to use. Maybe one of those
* two bits needs to be cleared, or there's something else in the
* CCR that needs tweaking. The pattern of resources suggests
* bit 0 turns on the ethernet, however...
