Subject: [dpdk-dev] [PATCH] net/i40e: fix wrong return value when handling PF message
Date: Wed, 21 Dec 2016 16:29:40 +0800 [thread overview]
Message-ID: <1482308980-76777-1-git-send-email-wenzhuo.lu@intel.com> (raw)
When VF receives a message from PF, it should check the return
value. But in i40evf_execute_vf_cmd the value is ignored and not
returned to the caller.
Fixes: 95cd21f45d1b ("i40evf: allocate virtchnl commands buffer per VF")
