Re: jumbo frames

[Kurt Kayser <kurt () noris de>]

Hi,

Isn't it a lot more cpu-intensive to 'collect' some 1500-byte frames
into some larger bucket, reassemble it into a jumbo-frame when the next
box has to chop it in order to send it out on a Sonet/PPP/etc interface which 
might have a smaller MTU again?

Doesn't make too much sense to me. I guess that was Tony's aim as well..
