Subject: [dpdk-dev] [dpdk-dev v2 1/1] net/ice: Support for GTPU down/up rss configure
Date: Fri, 10 Apr 2020 20:18:59 -0400 [thread overview]
Message-ID: <20200411001859.15472-2-jia.guo@intel.com> (raw)
In-Reply-To: <20200411001859.15472-1-jia.guo@intel.com>
Add GTP PDU uplink/donwlink checking in RSS inpust set configuration,
in order to support l3 src hash for GTPU uplink, while l3 dst hash
for GTPU downlink.
Signed-off-by: Jeff Guo <jia.guo@intel.com>
