[dpdk-dev] BPF in DPDK 18.05 as experimental

[Thomas Monjalon]

DPDK 18.05-rc3 will have a BPF experimental framework.

The symbols have been marked as experimental in the map file,
but the doxygen has no experimental mention,
the section in MAINTAINERS has not the EXPERIMENTAL tag,
and the API functions have not the attribute __rte_experimental.
Konstantin, please make a patch to make the experimental status clear.

Thanks
