From 02016804ed5e6a46f9162737bcdc78a3780332f5 Mon Sep 17 00:00:00 2001 From: Qi Zhang Date: Tue, 25 Sep 2018 10:34:31 +0800 Subject: [PATCH] net/i40e/base: properly clean resources 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.
