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 Signed-off-by: Lino Sanfilippo <LinoSanfilippo@gmx.de> Signed-off-by: David S. Miller <davem@davemloft.net>

If you have a network (Ethernet) card belonging to this class, say Y.

Note that the answer to this question doesn't directly affect the

kernel: saying N will just cause the configurator to skip all the

This driver supports Gigabit Ethernet adapters based on the
|
||||
Session Layer Interface (SLIC) technology by Alacritech.
|
||||
|
||||
Supported are Mojave (1 port) and Oasis (1, 2 and 4 port) cards,
|
||||
both copper and fiber.
|
||||
|
||||
To compile this driver as a module, choose M here: the module
|
||||
will be called slicoss. This is recommended.
