Copy buffer from rx ring.

Parameters

*	vm (in)
*	mif (in) pointer to memif interface
*	ring (in) pointer to memif ring
*	rd (in) pointer to ring data
ring_size	(in) ring size
*	n_free_bufs (in/out) the number of free vlib buffers available
**	first_b (out) the first vlib buffer pointer
*	first_bi (out) the first vlib buffer index
*	bi (in/out) the current buffer index #param * num_slots (in/out) the number of descriptors available to read

Returns

total bytes read from rx ring also written to vlib buffers
