doc: announce ethdev port id range increase

Browse Source 
This is an API/ABI change notice for DPDK 17.11 announcing the redefinition
of port_id. port_id is currently defined as uint8_t, which is limited to
the range 0 to 255. A larger range is required for vdev scalability.

It is necessary for a redefinition of port_id to extend it from 1 bytes to
2 bytes. All ethdev APIs and usages related to port_id will be changed at
the same time.

done by the EAL and not by the ``ethdev`` layer anymore. Users relying on this
flag being present only have to remove their checks to follow the change.
* ABI/API changes are planned for 17.11 in all structures which include port_id
definition such as "rte_eth_dev_data", "rte_port_ethdev_reader_params",
"rte_port_ethdev_writer_params", and so on. The definition of port_id will be
changed from 8 bits to 16 bits in order to support more than 256 ports in
DPDK. All APIs which have port_id parameter will be changed at the same time.
* librte_table: The ``key_mask`` parameter will be added to all the hash tables
that currently do not have it, as well as to the hash compute function prototype.
The non-"do-sig" versions of the hash tables will be removed
