Hi Stephen,

This is follow up to an existing patchset:
https://patches.dpdk.org/project/dpdk/list/?series=27400&state=*

Although field is addition to the "struct rte_eth_rss_conf" struct, it
is embedded into "struct rte_eth_conf" which is parameter to an API, so
change cause size increase in outer struct and causes ABI breakage,
requiring deprecation notice.
