Don't worry - It was simply kind of amusing that you told us "there is
a requirement to support ...." without the "in our project" part that
I expected.  Lets get back to (hopefully) solid facts.

This is an interesting question and probably you have an answer for
us?  Reading up on LLC I am not really sure what a CLI implementation
would give us - despite the need for a completely separate set of
tools to work with this protocol.  Using UDP (belonging to the IP
family) we can simply use the heapload of utilities available -
especially "netcat" comes to mind.

The netconsole support was written with this in mind to support (as
Wolfgang said) a seamless networking console for the U-Boot / Linux
combination.  The Linux netconsole support predates the netconsole in
U-Boot so it was clear that we would go for compatibility with this
implementation.

It is also not for posting complete quotes.  Please try to understand
that it is a waste of bandwidth and of our time to include these
completely useless text parts.  I can always look up the old mails if
I want to see these bits - E-Mail can be very efficient so please try
to use it in this spirirt - even if this entails the 15 minutes it
takes to read the netiquette.

Cheers

system with metaobject protocols [..] there is the potential for spectacular
failure modes if certain situations are not properly anticipated.
