Miller" <davem@...emloft.net> Subject: [PATCH 4.14 11/20] ibmvnic: Fix TX completion error handling From: Thomas Falcon <tlfalcon@...ux.ibm.com> [ Upstream commit ba246c175116e2e8fa4fdfa5f8e958e086a9a818 ] TX completions received with an error return code are not being processed properly. When an error code is seen, do not proceed to the next completion before cleaning up the existing entry's data structures.
