Subject: [dpdk-dev] [PATCH v2] net/ice: fix invalid RSS type
Date: Thu,  9 Jul 2020 15:50:20 +0800
Message-ID: <1594281020-457174-1-git-send-email-simei.su@intel.com> (raw)
In-Reply-To: <1594275994-318254-1-git-send-email-simei.su@intel.com>

When a RSS rule with only RSS type modifier L2/L3/L4 SRC/DST_ONLY,
it should return failure. This patch adds invalid RSS type check.

Fixes: dfaedcf20170 ("net/ice: refactor PF hash flow")

Signed-off-by: Simei Su <simei.su@intel.com>

v2:
* Add specific macro value in check rather than hard code.
