Subject: [PATCH net-2.6.25]  New driver "sfc" for Solarstorm SFC4000 controller
 - 5th attempt

This is a resubmission of a new driver for Solarflare network controllers.

The driver supports several types of PHY (10Gbase-T, XFP, CX4) on six
different 10G and 1G boards. There is a driver for the network controller
and an MTD driver that allows access to the flash/EEPROM.

NICs based on this controller are now available from SMC as part numbers
SMC10GPCIe-XFP and SMC10GPCIe-10BT.

FYI the previous thread was:
  http://marc.info/?l=linux-netdev&m=119999015817920&w=2

In previous postings we were asked to have the MTD part of this patch
reviewed and we have responded to the comments received so far:
  http://lists.infradead.org/pipermail/linux-mtd/2008-January/020355.html

Things that have changed since the last patch:
 - Removed residual support for more than one port per controller.
 - Moved LED control from PHY operations to board operations.
 - Added support for controlling LRO through ethtool {get,set}_flags().
 - Removed obsolete workaround for reservation of MSI-X tables by PCI core.
 - Improved reliability of PHY loopback setting.
 - Improved reliability of I2C operations.
 - Fixed on-load self-test when using RSS.
 - Simplified MTD driver following review on linux-mtd list.
 - Removed some redundant information from struct efx_nic.
 - hardware monitoring (for PHY link polling) is now a workqueue item
rather than using a timer
 - mac_lock becomes a mutex to support the previous item.

We would welcome more review of this code and would like to know if there
are any objections to this being merged for 2.6.25.
