Subject: [PATCH 2.6.21] phylib: Add support for Marvell 88e1111S and 88e1145

>From Andy Fleming <afleming@...escale.com>

Changes include:
* New support for 88e1145
* New support for 88e111s
* Fixing 88e1101 driver to not match non-88e1101 PHYs
* Increases in feature support across Marvell PHY product line
* Fixes a bunch of whitespace issues found by Lindent

Signed-off-by: Andrew Fleming <afleming@...escale.com>

This patch seems to have gotten lost.  It still applies cleanly, so I'm 
resubmitting it for 2.6.21.
