We now only allow per port preallocated buffers. We exchange the index into the array instead of passing the buffers around. We still use the refcount to track when a buffer can be reused. Improve API a little, allow passing the node as the first argument of the interface call. Implement alloc_buffer in v4l2 and improve the test.
