I had a look at the book "The Design and Implementation of the 4.4 BSD OS" but did not find an answer to this. The theoretical answer is 'yes'. Mbuf processing should deal with each mbuf individually, without regard to the chain its in. It is possible that some code doesn't obey this rule, but I don't know of any off-hand. It's easy to screw this up, so the possibility can't be ruled out, but it should work. Are you having problems, or just checking? Regards, Justin -- Justin C.
