+Subject: [PATCH] net: dsa: b53: Drop BCM5301x workaround for a wrong CPU/IMP
+ port
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On BCM5301x port 8 requires a fixed link when used.
+
+Years ago when b53 was an OpenWrt downstream driver (with configuration
+based on sometimes bugged NVRAM) there was a need for a fixup. In case
+of forcing fixed link for (incorrectly specified) port 5 the code had to
+actually setup port 8 link.
+
+For upstream b53 driver with setup based on DT there is no need for that
+workaround. In DT we have and require correct ports setup.
