phylib: Add support for Marvell 88e1111S and 88e1145
Andy Fleming [Sat, 10 Feb 2007 00:13:58 +0000 (18:13 -0600)]
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
