From 252de8f76b23a46ef7cc649dab8047893c3f4dd8 Mon Sep 17 00:00:00 2001 From: Thomas Falcon Date: Tue, 1 Dec 2020 09:52:11 -0600 Subject: [PATCH] ibmvnic: Fix TX completion error handling [ 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.
