Re: [Bridge] Bridging untagged and tagged VLANs

[Michael Tremer <michael.tremer@ipfire.org>]

Thanks for your answers.

In this mail on
http://www.mail-archive.com/bridge@lists.osdl.org/msg01440.html
there is the following sentence: "- Add native support for an untagged
vlan.  Currently an untagged
  vlan can be implimented using ebtables or similar."

Do you know how to do this? Seems to be the easiest way for me, because
I don't
think that I would be able to port this patch to 2.6. (But may be there
is somebody who
would like to do this. I want to put all these things into a linux
firewall www.ipfire.org, though there
is an efford for the open source community.)

Have you ever submitted this patch to the kernel developers?
