Use the just introduced Rules.make extension to clean up 
drivers/net/*/Makefile.

Group knowledge about building objects and linking them together
instead of splitting it between the top-level Makefile and
the per-directory Makefiles.

This change tries to keep the link order the same as it was, at least
as far as possible. One critical point is that we now link
the pcmcia / wireless netdrivers before the pcmcia subsystem.
However, the pcmcia subsystem is initialized via a late_initcall(),
so this shouldn't make a difference.

drivers/net/Makefile looks a bit long now, but that can be improved
a lot, patch yet to come.

Group selecting subdirs and linking them together. (Doesn't change
the link order)

autoirq_*() has been replaced by probe_irq_{on,off} a long time ago, so
it's about time to have it go away.

CONFIG_DEV_APPLETALK are meant for the same thing.  Rename
all uses to CONFIG_DEV_APPLETALK, use consistently inside
drivers/net/appletalk/Config.in and update documentation
to match.

net drivers to drivers/net/tulip directory.

'sungem' which DaveM is maintaining is the replacement.

from 2.4.x.
Also, remove deprecated SIOCDEVPRIVATE ioctl calls.

Via Dave Jones.

* Support new clone board.
* Count rx-lost-in-ring events.
* Support ethtool-compatible bitmapped printk message enable number.
* Support MII ethtool helper interface, and associated ioctls.
* Replace some MII-related magic numbers with linux/mii.h constants.
* Add in optional (and hopefully preferred... after testing) code
for resetting RX DMA engine on error.

* Support MII ethtool helper interface, and associated ioctls.
* Replace some MII-related magic numbers with constants from linux/mii.h.
* Remove deprecated SIOCDEVPRIVATE ioctls, SIOCxMIIxxx ioctl replacements
have been in place since 2.4.x.

* Support MII ethtool helper interface, and associated ioctls.
* Remove unused CP_CHIP_VERSION constant.
* Update to-do list in driver header.

* Support MII ethtool helper library, and associated ioctls.
* Replace some MII-related magic numbers with constants from linux/mii.h.
* Remove deprecated SIOCDEVPRIVATE ioctl usage, SIOCxMIIxxx is the
supported (and already present) replacement.

* Support MII ethtool helper interface, and related ioctls.
* Replace some MII-related magic numbers with constants.
