Subject: [dpdk-dev] [PATCH v10 2/3] ethdev: extend RSS offload types
Date: Fri, 4 Oct 2019 12:46:01 +0800 [thread overview]
Message-ID: <1570164362-64775-3-git-send-email-simei.su@intel.com> (raw)
In-Reply-To: <1570164362-64775-1-git-send-email-simei.su@intel.com>
This patch reserves several bits as input set selection from the
high end of the 64 bits. It is combined with exisiting ETH_RSS_*
to represent RSS types.
