Subject: [dpdk-dev] [PATCH v2] net/iavf: fix invalid RSS type
Date: Mon,  2 Nov 2020 10:04:19 +0800
Message-ID: <20201102020419.149961-1-simei.su@intel.com> (raw)
In-Reply-To: <20201030031638.370766-1-simei.su@intel.com>

When a RSS rule with symmetric hash function, the RSS type shouldn't
carry with SRC/DST_ONLY. This patch adds invalid RSS type check for
the case.

Fixes: 91f27b2e39ab ("net/iavf: refactor RSS")
