Subject: [dpdk-dev] [PATCH 09/20] net/i40e/base: properly clean resources
Date: Tue, 25 Sep 2018 10:34:31 +0800	[thread overview]
Message-ID: <20180925023442.134705-10-qi.z.zhang@intel.com> (raw)
In-Reply-To: <20180925023442.134705-1-qi.z.zhang@intel.com>

Allocated resources were not freed in the event of a failure in
i40e_init_lan_hmc function. This patch gracefully handles the fail
case after initializing the lan hmc.
