- I tried this, but then I hit issues with inlines.
Like for example:

static inline char * __rte_experimental
rte_mbuf_buf_addr(struct rte_mbuf *mb, struct rte_mempool *mp)
{
  return (char *)mb + sizeof(*mb) + rte_pktmbuf_priv_size(mp);
}

I did not find a way to move the __rte_experimental tag without getting
warnings.
If I try to compile some sources which includes rte_mbuf.h but without
-DALLOW_EXPERIMENTAL_API, then gcc errors at including the header,
complaining that rte_mbuf_buf_addr() is deprecated, even if this inline is
not called.

For now, I hid all those inlines under the ALLOW_EXPERIMENTAL_API flag.


- I have accumulated other fixes and I dropped all the marking in the .c
files.
This ended up with a huge series...

I will let the week end pass on this.
