[dpdk-dev] [PATCH 0/3] move mbuf definition into a separate file

Right now inclusion of rte_mbuf.h header can cause inclusion of
some arch/os specific headers.
That prevents it to be included directly by some
non-DPDK (but related) entities: KNI, BPF programs, etc.
To overcome that problem usually a separate definitions of rte_mbuf
structure is created within these entities.
That aproach has a lot of drawbacks: code duplication, error prone, etc.
This series moves rte_mbuf structure definition (and some related macros)
into a separate file that can be included by both rte_mbuf.h and
other non-DPDK entities.

Note that these moves shouldn't introduce any change for current DPDK code.

  eal: move CACHE and IOVA related definitions
  mbuf: move mbuf definition into a separate file
  examples/bpf: remove duplicate mbuf definition
