   * The SLICOSS driver for Alacritech's IS-NIC products.
   *
   * 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 actually tested on Oasis and Kalahari cards.
   *
   *
   * NOTE: This is the standard, non-accelerated version of Alacritech's
   *       IS-NIC driver.
