It would help to also know how the devices interact to answer the question of best location. Are the drivers for the coprocessor and for the queue manager mostly a pass-through for some operations (and some shared allocation of resources), i.e. more of a library, or is it a full-fledged driver that will service interrupts, etc? > My other question is on common header files (belonging to Queue > Manager) but is sourced > by Ethernet, where should those reside.

This depends somewhat on where the driver ends up, but somewhere under include/linux is likely the right place for the in-kernel interface header files. -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
