/*
* FILENAME: slicoss.c
*
* 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 acutally tested on Oasis and Kalahari cards.
*
*
* NOTE: This is the standard, non-accelerated version of Alacritech's
* IS-NIC driver.
