Subject: [dpdk-dev] [PATCH v2] net/iavf: fix unchecked Tx cleanup error
Date: Mon, 19 Oct 2020 13:42:53 +0800	[thread overview]
Message-ID: <20201019054253.105559-1-leyi.rong@intel.com> (raw)
In-Reply-To: <20201014082857.81080-1-leyi.rong@intel.com>

Coverity complains of unchecked return value warning of
iavf_xmit_cleanup, while this cleanup is opportunistic and will not cause
problems if it fails. So instead of checking the return value of
iavf_xmit_cleanup and return in case of cleanup failure, we directly cast
it to void function to make the Coverity happy.

Coverity issue: 363045
Fixes: 02d212ca3125 ("net/iavf: rename remaining avf strings")
Cc: stable@dpdk.org
