Is something wrong with netdev? Seems like it is offlined and polls every
24 hours or so.

;-> i think you are totaly misunderstanding me.
If the ethertype is IPX it goes to IPX. If the ethertype is your protocol
it goes to your protocol.
There is _no_ protocol violation. So how does this require me to change
IPX?
The only reason you need to extend (not change) IP is because 'routing'
(which appears to be a major requirement) is a function of IP.
The hooks are already there!

Ok, so do you use ifconfig to attach a vlan to a device? And why not?
Sure go ahead and extend ifconfig so now it knows about attaching and
deleting VLANs on a device. After all, it is another interface ;->
A VLAN is a way of logically separating traffic, across the same device
(or equipment)
Device being a physical entity; i would prefer to call a VLAN a circuit
And sure i dont mind re-writting ifconfig so it knows about such things.
But i dont know if it would still be called ifconfig.

I really fail to see how you reached the conclusion above after all that
head banging.

I am not ruling out IPX or Gleb's protocol. If IPX was so important
why are we "routing", which is an IP term? I understand there are legacy
protocols such as appletalk etc which have to be supported.
In their native form they work just fine today over Linux.
If you want to wrap them in a VLAN, how is my proposal stopping you?

Why dont you take up the challenge and write up an RFC? Its not about
what "survives"; its about what a good solution is. "Survival" with
a technical twist is a corporate political term. Normally, it is
driven by how colorful your chartware is. We are above that.
So go ahead and write something up so we dont resort to the "he said,
she said".
