Hi, This is a re-post of the be2net driver incorporating fixes for review comments received: - sparse warnings, especially __iomem type checking - an earlier comment by Patrick McHardy to disable vlan hardware filtering when the number of configured vlans exceeds number of supported vlans. The code is also available in a single patch file at ftp://ftp.serverengines.com/be2net.patch (anonymous) The patches are against the Linus git tree. Thanks, -Sathya P.S: Pls ignore the "company confidential" warning at the end of the patch emails.
