Rx ports use queues referred to as “free descriptor/buffer queues” to allocated empty host type descriptors. The entries on the Free Descriptor/Buffer Queues have pre-attached empty buffers whose size and location are described in the “original buffer information” fields in the descriptor. The host is required to allocate both the descriptor and buffer and pre-link them prior to adding a descriptor to a free descriptor/buffer queue.
