1 /* sbni.c: Granch SBNI12 leased line adapters driver for linux
3 * Written 2001 by Denis I.Timofeev (timofeev@granch.ru)
5 * Previous versions were written by Yaroslav Polyakov,
6 * Alexey Zverev and Max Khon.
8 * Driver supports SBNI12-02,-04,-05,-10,-11 cards, single and
9 * double-channel, PCI and ISA modifications.
10 * More info and useful utilities to work with SBNI12 cards you can find
11 * at http://www.granch.com (English) or http://www.granch.ru (Russian)
13 * This software may be used and distributed according to the terms
14 * of the GNU General Public License.
18 * - Fixed bug in probe
20 * - Driver was completely redesigned by Denis I.Timofeev,
21 * - now PCI/Dual, ISA/Dual (with single interrupt line) models are
23 * 3.3.0 Thu Feb 24 21:30:28 NOVT 2000
25 * 3.2.0 Mon Dec 13 22:26:53 NOVT 1999
26 * - Completely rebuilt all the packet storage system
27 * - to work in Ethernet-like style.
28 * 3.1.1 just fixed some bugs (5 aug 1999)
29 * 3.1.0 added balancing feature (26 apr 1999)
30 * 3.0.1 just fixed some bugs (14 apr 1999).
31 * 3.0.0 Initial Revision, Yaroslav Polyakov (24 Feb 1999)
32 * - added pre-calculation for CRC, fixed bug with "len-2" frames,
33 * - removed outbound fragmentation (MTU=1000), written CRC-calculation
34 * - on asm, added work with hard_headers and now we have our own cache
35 * - for them, optionally supported word-interchange on some chipsets,
37 * Known problem: this driver wasn't tested on multiprocessor machine.
