Subject: [dpdk-dev] [PATCH v3 03/13] e1000: replace rte_panic instances in e1000 driver
Date: Fri, 13 Apr 2018 21:30:34 +0300	[thread overview]
Message-ID: <1523644244-17511-4-git-send-email-arnon@qwilt.com> (raw)
In-Reply-To: <1523644244-17511-1-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
