|
| + * The actual driving is done by main.c, this is just resource
|
| + * allocation stuff.
|
| + *
|
| + * This driver is modeled after the orinoco_plx driver. The main
|
| + * difference is that the TMD chip has only IO port ranges and doesn't
|
| + * provide access to the PCMCIA attribute space.
|
| + *
|
| + * Pheecom sells cards with the TMD chip as "ASIC version"
