From: Huisong Li <lihuis...@huawei.com>
The settings of RSS types comes from the ethdev ops (like, dev_configure
and rss_hash_update) and rte_flow API. For the ethdev ops, driver has to
save it so as to it can be restored when reset is triggered.
While rte_flow API no need to maintain this field, it can be restored by
the saved rule.
