This paves the way for a variety of more interesting interactions between drivers and the stack which are currently not possible (e.g. checksum offload, #18744). The main advantage for the moment is that we will save a memcpy of the buffer on each send/receive. Adapt the virtio_net driver so that at least one driver is using the new interface. Network still seems to work OK with it. Change-Id: Ic5832e4865e3e1bed7462583ca1ffd16418d7cab Reviewed-on: https://review.haiku-os.org/c/haiku/+/7912 Reviewed-by: waddlesplash <waddlesplash@gmail.com>
