Subject: [dpdk-dev] [PATCH v2] net/iavf: fix wrong bandwidth unit in TM capability querying
Date: Thu, 15 Jul 2021 18:36:06 +0800 [thread overview]
Message-ID: <20210715103606.13551-1-ting.xu@intel.com> (raw)
In-Reply-To: <20210715020811.15577-1-ting.xu@intel.com>
In IAVF node TM capability querying, the unit of bandwidth is Kbps,
which is not correct according to TM specification. Change the unit to
Byte per second. Refine some unclear comments as well.
Fixes: 44d0a720a538 ("net/iavf: query QoS capabilities and set queue TC mapping")
