Subject: [dpdk-dev] [PATCH] vhost: added error log in vhost_user_set_features
Date: Fri, 16 Jun 2017 16:32:05 +0200 [thread overview]
Message-ID: <1497623525-163750-1-git-send-email-dariuszx.stojaczyk@intel.com> (raw)
Since vhost_user_set_features failure is not handled in any way, a
single error log has been added to at least to let the user know that
something has gone wrong.
