Subject: [dpdk-dev] [PATCH v2] net/ice: fix GTPU down/uplink and extension conflict
Date: Fri, 24 Jul 2020 22:41:52 +0800 [thread overview]
Message-ID: <1595601712-403946-1-git-send-email-simei.su@intel.com> (raw)
In-Reply-To: <1595556601-87800-1-git-send-email-simei.su@intel.com>
When adding a RSS rule with GTPU_DWN/UP, it will write from top to
bottom for profile due to firmware limitation. If a RSS rule with
GTPU_EH already exists, then GTPU_DWN/UP packet will match GTPU_EH
profile. This patch solves this issue by remembering a gtpu_eh RSS
configure and removing it before the corresponding RSS configure
for downlink/uplink rule is issued.
Fixes: 2e2810fc1868 ("net/ice: fix GTPU RSS")

v2:
* Refine commit message.
* Clean code.
* Fix gtpu down/uplink can't be issued simultaneously.
* Fix gtpu down/uplink ipv4_udp/tcp or ipv6_udp/tcp for symmetric
rule can't take effect.
