Hi Dave,

(Kinda jumping in here, sorry!)

Have you more info about these PPPoE messages for line rate? We'd like
to use this with our product (we're an ISP in the UK), but sending the
tx/rx rate isn't in the PPP spec itself, so we'd be inventing new
messages. (or are the German devices getting the line rates from a DSL
modem?)

Thanks.
