+Subject: [PATCH 35/48] net: dsa: mt7530: correct port capabilities of MT7988
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On the switch on the MT7988 SoC, as shown in Block Diagram 8.1.1.3 on page
+125 of "MT7988A Wi-Fi 7 Generation Router Platform: Datasheet (Open
+Version) v0.1", there are only 4 PHYs. That's port 0 to 3. Set the case for
+ports which connect to switch PHYs to '0 ... 3'.
+
+Port 4 and 5 are not used at all in this design.
