+Subject: [PATCH] net: phy: Fix qca8081 with speeds lower than 2.5Gb/s
|
|
+
|
|
+A typo in qca808x_read_status means we try to set SMII mode on the port
|
|
+rather than SGMII when the link speed is not 2.5Gb/s. This results in no
|
|
+traffic due to the mismatch in configuration between the phy and the
|
|
+mac.
|
|
+
|
|
+v2:
|
|
+ Only change interface mode when the link is up
|
|
+
|
|
+Fixes: 79c7bc0521545 ("net: phy: add qca8081 read_status")
