+Subject: [PATCH net-next 1/2] net: ethernet: mediatek: split tx and rx fields
+ in mtk_soc_data struct
+
+Split tx and rx fields in mtk_soc_data struct. This is a preliminary
+patch to roll back to QDMA for MT7986 SoC in order to fix a hw hang
+if the device receives a corrupted packet.

+ ADMAv2 on MT7981 and MT7986
+
+ADMA is plagued by RX hangs which can't easily detected and happen upon
+receival of a corrupted package.
+Use QDMA just like on netsys v1 which is also still present and usable, and
+doesn't suffer from that problem.

+Subject: [PATCH net-next 2/2] net: ethernet: mediatek: use QDMA instead of
+ ADMAv2 on MT7981 and MT7986
+
+ADMA is plagued by RX hangs which can't easily detected and happen upon
+receival of a corrupted package.
+Use QDMA just like on netsys v1 which is also still present and usable, and
+doesn't suffer from that problem.
