Tom Gundersen c835a67733 net: set name_assign_type in alloc_netdev() 
Extend alloc_netdev{,_mq{,s}}() to take name_assign_type as argument, and convert
all users to pass NET_NAME_UNKNOWN.

/* sbni.c: Granch SBNI12 leased line adapters driver for linux
*
* Written 2001 by Denis I.Timofeev (timofeev@granch.ru)
*
* Previous versions were written by Yaroslav Polyakov,
* Alexey Zverev and Max Khon.
*
* Driver supports SBNI12-02,-04,-05,-10,-11 cards, single and
* double-channel, PCI and ISA modifications.
* More info and useful utilities to work with SBNI12 cards you can find
* at http://www.granch.com (English) or http://www.granch.ru (Russian)
*
* This software may be used and distributed according to the terms
* of the GNU General Public License.
*
*
* 5.0.1 Jun 22 2001
* - Fixed bug in probe
* 5.0.0 Jun 06 2001
* - Driver was completely redesigned by Denis I.Timofeev,
* - now PCI/Dual, ISA/Dual (with single interrupt line) models are
* - supported
* 3.3.0 Thu Feb 24 21:30:28 NOVT 2000
* - PCI cards support
* 3.2.0 Mon Dec 13 22:26:53 NOVT 1999
* - Completely rebuilt all the packet storage system
* - to work in Ethernet-like style.
* 3.1.1 just fixed some bugs (5 aug 1999)
* 3.1.0 added balancing feature (26 apr 1999)
* 3.0.1 just fixed some bugs (14 apr 1999).
* 3.0.0 Initial Revision, Yaroslav Polyakov (24 Feb 1999)
* - added pre-calculation for CRC, fixed bug with "len-2" frames,
* - removed outbound fragmentation (MTU=1000), written CRC-calculation
* - on asm, added work with hard_headers and now we have our own cache
* - for them, optionally supported word-interchange on some chipsets,
*
* Known problem: this driver wasn't tested on multiprocessor machine.
