Subject: [dpdk-dev] [PATCH v4 06/11] kni: replace rte_panic instances in kni
Date: Thu, 19 Apr 2018 09:01:04 +0300 [thread overview]
Message-ID: <1524117669-25729-7-git-send-email-arnon@qwilt.com> (raw)
In-Reply-To: <1524117669-25729-1-git-send-email-arnon@qwilt.com>
replace panic calls with log and retrun value.
Local function to this file,
changing from void to int is non-abi-breaking
