Subject: [dpdk-dev] [PATCH] enic: fix build on SUSE 11
Date: Mon, 15 Dec 2014 12:07:29 +0100	[thread overview]
Message-ID: <1418641649-4277-1-git-send-email-thomas.monjalon@6wind.com> (raw)
In-Reply-To: <19703944.gAxOdpYSXo@xps13>

GCC 4.5.1 from SUSE throws this error:
	lib/librte_pmd_enic/enic_main.c:862:2: error: value computed is not used

It seems to be a GCC bug.
