Subject: [dpdk-dev] [PATCH v3] net/ice: support show RSS hash configuration
Date: Thu, 29 Oct 2020 14:37:57 +0800 [thread overview]
Message-ID: <20201029063757.2145-1-taox.zhu@intel.com> (raw)
In-Reply-To: <20201029051129.784-1-taox.zhu@intel.com>
From: Zhu Tao <taox.zhu@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.
