[dpdk-dev] [PATCH v3] net/ice: support show RSS hash configuration

Thu Oct 29 07:37:57 CET 2020
From: Zhu Tao <taox.zhu at intel.com>
Implement interface 'ice_rss_hash_conf_get' to support show RSS
hash configuration.
Note:
Not support the same time setting RSS with RTE and classify API.
Only return rss_hf from latest dev_configure or dev_rss_hash_update.
All configures from rte_flow are ignored.
