Manual merge of rsync://rsync.kernel.org/pub/scm/linux/kernel/git/jgarzik/netdev-2.6.git
This is a fixed-up version of the broken "upstream-2.6.13" branch, where I re-did the manual merge of drivers/net/r8169.c by hand, and made sure the history is all good.

29 * The Schneider & Koch (SK) G16 Network device driver is based
30 * on the 'ni6510' driver from Michael Hipp which can be found at
31 * ftp://sunsite.unc.edu/pub/Linux/system/Network/drivers/nidrivers.tar.gz
32 *
33 * Sources: 1) ni6510.c by M. Hipp
34 * 2) depca.c by D.C. Davies
35 * 3) skeleton.c by D. Becker
36 * 4) Am7990 Local Area Network Controller for Ethernet (LANCE),
37 * AMD, Pub. #05698, June 1989
38 *
39 * Many Thanks for helping me to get things working to:
40 *
41 * A. Cox (A.Cox@swansea.ac.uk)
42 * M. Hipp (mhipp@student.uni-tuebingen.de)
43 * R. Bolz (Schneider & Koch, Germany)
44 *
45 * To Do:
46 * - Support of SK_G8 and other SK Network Cards.
47 * - Autoset memory mapped RAM. Check for free memory and then
48 * configure RAM correctly.
49 * - SK_close should really set card in to initial state.
50 * - Test if IRQ 3 is not switched off. Use autoirq() functionality.
51 * (as in /drivers/net/skeleton.c)
52 * - Implement Multicast addressing. At minimum something like
53 * in depca.c.
54 * - Redo the statistics part.
55 * - Try to find out if the board is in 8 Bit or 16 Bit slot.
56 * If in 8 Bit mode don't use IRQ 11.
57 * - (Try to make it slightly faster.)
58 * - Power management support

374 * The Network components are: dual ported RAM, Prom, I/O Reg, Status-,

376 *
377 * dual ported RAM: This is the only memory region which the LANCE chip
378 * has access to. From the Lance it is addressed from 0x0000 to
379 * 0x3fbf. The host accesses it normally.
380 *
381 * PROM: The PROM obtains the ETHERNET-MAC-Address. It is realised as a
382 * 8-Bit PROM, this means only the 16 even addresses are used of the
383 * 32 Byte Address region. Access to an odd address results in invalid
384 * data.
385 *
386 * LANCE I/O Reg: The I/O Reg is build of 4 single Registers, Low-Byte Write,
387 * Hi-Byte Write, Low-Byte Read, Hi-Byte Read.
388 * Transfer from or to the LANCE is always in 16Bit so Low and High
389 * registers are always relevant.
390 *
391 * The Data from the Readregister is not the data in the Writeregister!!
392 *
393 * Port: Status- and Controlregister.
394 * Two different registers which share the same address, Status is
395 * read-only, Control is write-only.
396 *
397 * I/O Command:
398 * Any bitcombination written in here starts the transmission between
399 * Host and LANCE.
