[PATCH] [RFC] New driver "sfc" for Solarstorm SFC4000 controller

[Ben Hutchings <bhutchings@solarflare.com>]

This is a net driver (and MTD driver, sfc_mtd) for our SFC4000 10G
Ethernet controller, branded "Solarstorm", with various PHYs.  It is
intended to support our NIC reference designs SFE4001 (10GBASE-T),
SFE4002 (XFP), SFE4003 (10GBASE-CX4), OEM designs based on them, and
some development boards.  We have been maintaining drivers out-of-tree
for some time but are now preparing them to work in-tree.

There are some issues that might need to be addressed:

1. When we enable NAPI polling, we need to set __LINK_STATE_START in
   the net device used for NAPI.  This bit is commented as private in
   netdevice.h, but e1000 also does this.  Is this incorrect?

2. We added a lot of definitions and code for 10G MDIO.  This is mostly
   generic and could be moved into core code.

We welcome review comments and are ready to address them.
