net: ethernet: slicoss: add slicoss gigabit ethernet driver

Add driver for Alacritech gigabit ethernet cards with SLIC (session-layer
interface control) technology. The driver provides basic support without
SLIC for the following devices:

- 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

+	  Session Layer Interface (SLIC) technology by Alacritech.
+
+	  Supported are Mojave (1 port) and Oasis (1, 2 and 4 port) cards,
