3-digit VLAN tagging

[GoogleCodeExporter]

Dear Sir, may I know how to enable the 3-digit VLAN tagging under version 
"tomato-WRT54G_WRT54GL-1.28.0021Teaman-VLAN-Std" please?

I would like to add vlan500 and vlan600 as VLAN tagging.

Thank you in advance for your great help!

Anson

There's some good news (as well as a fair chunk of not-so-good news...).

Good news: it /is/ possible to use pretty much any value for VLAN IDs, even on 
such 'ancient' devices like those WRT54GL of yours/mine ;) 

There's quite a bit of work already done by Fedor and lly on the 'base' 
tomatoUSB branch (vlan0tag support VLAN initialization fixes, originally from 
wl500g.googlecode.com).

This so-called 'vlan0tag' thing is actually the name of a very special NVRAM 
var: when/if set, its value will be used as a 'base VID' - sorta like a 
'prefix' or a 'starting point' for mapping vlanX interfaces to a different set 
of VLAN tags/IDs.

Not-so-good news: if set, vlan0tag must be a multiple of 16 (or zero/unset) and 
you're still restricted to have/use a maximum of 16 VLANs (which will be 
assigned to a contiguous block of 16 VIDS, just 'shifted' a few bits). This 
seems to be related to HW limitations (BCM5325, if I'm not mistaken).

Then... there's been quite a few new models since our devices, like the E3000 
(which seems to have a BCM53115 switch). For many of those (more 
recent/new-ish) devices, it seem to be actually /possible/ to assign and use 
pretty much any kind of config/settings you could think of ;)

Hi its glad that tomato the favourite of mine now support 3digit vlan. It's 
there a simple step by step to do so ? Or I just meet to flash the firmware and 
it will all there ? Thanks for advance.
