8 * Driver supports SBNI12-02,-04,-05,-10,-11 cards, single and
9 * double-channel, PCI and ISA modifications.
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
22 * - supported
24 * - PCI cards support
26 * - Completely rebuilt all the packet storage system
27 * - to work in Ethernet-like style.
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,
85 /* transmitting frame number - from frames qty to 1 */

92 error - while receiver tunes on opposite side of wire */
