- Allocate the data buffers instead of using the default inline rte_mbuf
layout.
- Implement an rx_gc() and add an _rx_gc_poller to call it: we will refill
the rx mbuf's when at least 64 free buffers.
This threshold has been chosen as a sane enough number.
- Introduce the mbuf_data_size == 4K. Allocate 4K buffers for a detached flow.
We are still going to allocate 2K data buffers for an inline case since 4K
buffers would require 2 pages per mbuf due to "mbuf_overhead".
