[Sidewinder] VLAN Support

[Sidewinder moderated discussion list]

I have a 6.x Sidewinder G2 on which I wish to enable VLAN support for
the internal adapter/burb.  The trouble is, documentaiton seems to be
sorely lacking.

For instance:

Is a reboot necessary after turning on VLAN support?

Do existing rules need to be adjusted afterward?

Will the adapter reset (will there be a service outage)?

How does one fall back in the case of failure?

You get the idea.  Has anyone VLAN-enabled their interface on an
existing Sidewinder G2, and, if so, what advice can you give and gotchas
can you warn against?

Thank you.

Also, I'm surprised at my inability to locate any Sidewinder folks on
Twitter.
