       The generic rte_mbuf, containing a packet mbuf.

       Definition at line 467 of file rte_mbuf_core.h.

void*buf_addr
       Virtual address of segment buffer.

       Definition at line 468 of file rte_mbuf_core.h.

   structrte_mbuf*next
       Next segment of scattered packet. This field is valid when physical address field is undefined. Otherwise
       next pointer in the second cache line will be used.

       Definition at line 485 of file rte_mbuf_core.h.

   uint16_trefcnt
       Reference counter. Its size should at least equal to the size of port field (16 bits), to support zero-
       copy broadcast. It should only be accessed using the following functions: rte_mbuf_refcnt_update(),
       rte_mbuf_refcnt_read(), and rte_mbuf_refcnt_set(). The functionality of these functions (atomic, or non-
       atomic) is controlled by the RTE_MBUF_REFCNT_ATOMIC flag.
