-Subject: [PATCH 086/102] net-next: mediatek: add next data pointer coherency
- protection
-
-The QDMA engine can fail to update the register pointing to the next TX
-descriptor if this bit does not get set in the QDMA configuration register.
-Not setting this bit can result in invalid values inside the TX rings
-registers which will causes TX stalls.
