The attached patch adds support for VLANs to the sis900 driver and bumps the version number. It is based on an old (2003) patch for the 2.4 series by Hamid Hashemi Golpayegani. It applies on top of 2.6.16(.5). I have one report that it works and behaves as intended. Please review and consider for inclusion.
