+  Enable RGMII connected Quantenna module on MT7621.
+
+  The Mitrastar designed ZyXEL WAP6805 has a Quantenna QV840
+  module connected to the RGMII pins of the MT7621 SoC. For
+  unknown reasons, it is necessary to change the value of
+  the register at 0x1e110008 from default (usually 0xc000c)
+  to 0x9000c for this connection wo work.
+
+  This driver simply does that without much fuzz.
