doc: announce ABI change for link speed

A rework was prepared by Marc Sune:
http://dpdk.org/ml/archives/dev/2015-October/026037.html
The goal is to retrieve the supported link speed of a device
and to allow 100G devices while having a consistent API.

+* 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 entries (8 bits) while newer NICs support larger
   tables (512 entries).
