 * This driver is supposed to support:
 *
 *      Mojave cards (single port PCI Gigabit) both copper and fiber
 *      Oasis cards (single and dual port PCI-x Gigabit) copper and fiber
 *      Kalahari cards (dual and quad port PCI-e Gigabit) copper and fiber
 *
 * The driver was acutally tested on Oasis and Kalahari cards.
