This series resolves a few issues in the ibmvnic driver's
RX buffer and TX completion processing. The first patch
includes memory barriers to synchronize queue descriptor
reads. The second patch fixes a memory leak that could
occur if the device returns a TX completion with an error
code in the descriptor, in which case the respective socket
buffer and other relevant data structures may not be freed
or updated properly.
v2: Provide more detailed comments explaining specifically what
reads are being ordered, suggested by Michael Ellerman
Thomas Falcon (2):
ibmvnic: Ensure that SCRQ entry reads are correctly ordered
ibmvnic: Fix TX completion error handling
