[PATCH net 2/2] ibmvnic: Fix TX completion error handling
From: Thomas Falcon <hidden>
Date: 2020-11-24 17:32:06

netdev
Subsystem:
ibm power sriov virtual nic device driver, linux for powerpc (32-bit and 64-bit), networking drivers, the rest · Maintainers:
Haren Myneni, Rick Lindsley, Madhavan Srinivasan, Michael Ellerman, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
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.
Fixes: 032c5e828 ("Driver for IBM System i/p VNIC protocol")
