  42  * The SLICOSS driver for Alacritech's IS-NIC products.
  43  *
  44  * This driver is supposed to support:
  45  *
  46  *      Mojave cards (single port PCI Gigabit) both copper and fiber
  47  *      Oasis cards (single and dual port PCI-x Gigabit) copper and fiber
  48  *      Kalahari cards (dual and quad port PCI-e Gigabit) copper and fiber
  49  *
  50  * The driver was actually tested on Oasis and Kalahari cards.
  51  *
