No goal in doing that, no - it wasn't a conscious decision.

[-- Attachment #1: natsemi-ignore-phy.patch --]
[-- Type: text/plain, Size: 4353 bytes --]
This patch provides code paths which allow the natsemi driver to use the
external MII port on the chip but ignore any PHYs that may be attached to it.
The link state will be left as it was when the driver started and can be
configured via ethtool. Any PHYs that are present can be accessed via the MII
ioctl()s.
This is useful for systems where the device is connected without a PHY
or where either information or actions outside the scope of the driver
are required in order to use the PHYs.

This revision of the patch fixes some issues brought up during review.
Previous versions of this patch exposed the new functionality as a module
option. This has been removed. Any hardware that needs this should be
identifiable by a quirk since it unlikely to behave correctly with an
unmodified driver.

[-- Attachment #1: natsemi-ignore-phy.patch --]
[-- Type: text/plain, Size: 5586 bytes --]
This patch provides code paths which allow the natsemi driver to use the
external MII port on the chip but ignore any PHYs that may be attached to it.
The link state will be left as it was when the driver started and can be
configured via ethtool. Any PHYs that are present can be accessed via the MII
ioctl()s.
This is useful for systems where the device is connected without a PHY
or where either information or actions outside the scope of the driver
are required in order to use the PHYs.
Signed-Off-By: Mark Brown <broonie@sirena.org.uk>
---
Previous versions of this patch exposed the new functionality as a module
option. This has been removed. Any hardware that needs this should be
identifiable by a quirk since it unlikely to behave correctly with an
unmodified driver.
