sfc: Changes for 2.6.29

This patch series includes one bug fix also submitted for .28, and a number of features that were removed from the out-of-tree driver before submission and have now been simplified and cleaned up.

The MTD driver exposes only the flash partition used for the "expansion ROM". We are working on gPXE support for our boards and this makes it easy for users and developers to update their boards. We do not want to expose flash through the ethtool EEPROM access functions because they are unsuitable for flash and we already map them to the gPXE configuration partition which really is in EEPROM.

The hardware monitoring code is now mostly contained in the lm87 and lm90 drivers. We just configure the sensor limits as necessary and shut down the PHY in case of an alarm.

Driverlink provides an API to share the NIC's resources with other drivers that implement hardware-assisted network device virtualisation. This has already been used to good effect in Xen Linux. We hope to do the same for mainline Linux kernels acting as a hypervisor or dom0.

Ben.
