With support for segmented packets, it is now possible to easily receive packets of many sizes, given an adequate number of descriptors.
Remove limitation on the minimum size of mbuf: on reception, if a packet won't fit in the queue's mbufs, it will be detected in the packet info and the packet will be discarded.
