ethdev: increase RETA entry size

Browse Source 
Several NICs can handle 512 entries/queues in their RETA table,
an 8 bit field is not large enough for them.

* The ethdev structures rte_eth_link, rte_eth_dev_info and rte_eth_conf
must be updated to support 100G link and to have a cleaner link speed API.
* ABI changes is planned for the reta field in struct rte_eth_rss_reta_entry64
which handles at most 256 queues (8 bits) while newer NICs support larger
tables (512 queues).
It should be integrated in release 2.3.
* ABI changes are planned for struct rte_eth_fdir_flow in order to support
extend flow director's input set. The release 2.2 does not contain these ABI
changes, but release 2.3 will, and no backwards compatibility is planned.
