SiS 900 ethernet driver in Solaris

On my PC I have the SiS 900 onboard ethernet driver. This did not work reliable
in OpenSolaris.

After some search I found a disccusion on with a link to upgrade
the driver.

Here is the link to the driver, which is a little bit newer than my installed version.

This allowed the upgrade of the installed image with a reliable network connection.
