Subject: [PATCH net] net: phy: Fix qca8081 with speeds lower than 2.5Gb/s
Date: Sun, 30 Jan 2022 10:25:28 +0000 [thread overview]
Message-ID: <YfZnmMteVry/A1XR@earth.li> (raw)
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.
Fixes: 79c7bc0521545 ("net: phy: add qca8081 read_status")
Signed-off-by: Jonathan McDowell <noodles@earth•li>
