41 *
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 *
52 *
53 * NOTE: This is the standard, non-accelerated version of Alacritech's
54 * IS-NIC driver.
