Subject: [PATCH 6/9][TG3]: Add basic 5906 support.

From: "Michael Chan" <[email-masked]>
Date: Wed, 27 Sep 2006 13:34:59 -0700

[TG3]: Add basic 5906 support.

Add support for the new 5709 device.  This is a new 10/100 Mbps chip.
The mailbox access and firmware interface are quite different from
all other tg3 chips.
