Bloating kernel memory is not the right answer. Solaris comes with a quite effective POSIX threads library (standard since 1996) which makes it easy to quickly shuttle the data into a buffer in your own application. One thread deals with the network while the other thread deals with the device. I imagine that this is what the supreme mbuffer program is doing.
