Colin Ian King 5618c8e24a net: dl2k: remove redundant re-assignment to np
The pointer np is initialized and then re-assigned the same value
a few lines later. Remove the redundant duplicated assignment. Cleans
up clang warning:

drivers/net/ethernet/dlink/dl2k.c:314:25: warning: Value stored to
'np' during its initialization is never read

Instead of using a private copy of struct net_device_stats in struct

Javier Martinez Canillas 067577868b sundance: use IS_ENABLED() instead of checking for built-in or module
The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either
built-in or as a module, use that macro instead of open coding the same.

Using the macro makes the code more readable by helping abstract away some
of the Kconfig built-in and module enable details.

Ondrej Zary 1777ddb84a dl2k: Implement suspend
Add suspend/resume support to dl2k driver.
This requires RX/TX rings to be reset so split out the required
functionality from alloc_list() into new rio_reset_ring().

Tested on Asus NX1101 (IP1000A) and D-Link DGE-550T (DL-2000).

Ondrej Zary c3f45d322c dl2k: Add support for IP1000A-based cards
Add support for IP1000A chips to dl2k driver.
IP1000A chip looks like a TC9020 with integrated PHY.

This allows IP1000A chips to work reliably because the ipg driver is
buggy - it loses packets under load and then completely stops
transmitting data.

Tested with Asus NX1101 v2.0 at 10, 100 and 1000Mbps:
vendor=0x13f0 device=0x1023 (rev 0x41)
subsystem vendor=0x1043 device=0x8180

MAC address registers access needed to be changed from 8-bit to 16-bit
because 8-bit does not work on IP1000A. 8-bit access is not even
allowed in the TC9020 datasheet (although it worked). 16-bit access
works on both.

Tested that it does not break D-Link DGE-550T (DL-2000 chip, probably
a rebranded TC9020):
vendor=0x1186 device=0x4000 (rev 0x0c)
subsystem vendor=0x1186 device=0x4000

Paul Gortmaker 138b15ed87 drivers/net: remove all references to obsolete Ethernet-HOWTO
This howto made sense in the 1990s when users had to manually configure
ISA cards with jumpers or vendor utilities, but with the implementation
of PCI it became increasingly less and less relevant, to the point where
it has been well over a decade since I last updated it.  And there is
no value in anyone else taking over updating it either.

However the references to it continue to spread as boiler plate text
from one Kconfig file into the next.  We are not doing end users any
favours by pointing them at this old document, so lets kill it with
fire, once and for all, to hopefully stop any further spread.

No code is changed in this commit, just Kconfig help text.
