Subject: [PATCH 00/16] MDIO and ethtool enhancements

The first part of this series introduce counterparts to <linux/mii.h>
and the mii module for use with MDIO clause 45 devices and controllers
that support both clause 22 and clause 45, and change several 10G
Ethernet drivers to use them.

The remaining patches are a bit miscellaneous:
- Extend generic flow control/pause frame support and change the sfc
driver to use it
- Add fields to the ethtool_cmd structure to report the supported MDIO
mode(s) and link partner advertising flags, and implement these in the
mdio and mii modules
- Add support for backplane (1000BASE-KR and 10GBASE-KR/KX4) modes to
ethtool and the mdio module

I have a few questions to be resolved:
- Is the naming of functions and constants in <linux/mdio.h> reasonable,
or is more qualification required?
- Is it reasonable to carry on using the MII ioctl interface with flags?
- Are there more drivers that could use these generic definitions (I
haven't looked at the Broadcom drivers yet)?
- Does the backplane code work at all (I don't have any suitable
hardware yet)?

Ben.
