This is effectlively what Luigi did with his 'flow pointer' however it probably should be an extensible scheme so that new 'hacks' can be added to the system and make use of it. the trouble with just using a pointer to something is that the something needs to be freed some time. and it may need to be allocated at unknown spl etc. Luigi found that there were a lot of places tha had to be hackedto know about the new pointer. julian On Tue, 28 Jul 1998, Garrett Wollman wrote: > <<On Mon, 27 Jul 1998 16:55:58 -0700 (PDT), Julian Elischer <julian@whistle.com> said: > > > trouble is that there needs to be some place to store data > > on a 'packet by packet' basis, The data is generated at one point in > > processing and needed at another.. > > Stick it in the (mbuf) packet header.
