A connection is shown but data transmission is not possible. Note that this patch is only for the "current" kernel. The "edge" kernel no longer boots RockPI-S. Jira reference number AR-1904 How Has This Been Tested? Built 23.05 Minimal image for RockPI-S Please describe the tests that you ran to verify your changes. Please also note any relevant details for your test configuration. Verified Ethernet transfer @100Mbit/s initially ethtool -s end0 advertise 3 Verified Ethernet transfer rate now only 10Mbit/s ethtool -s end0 advertise f Verified Ethernet transfer rate restored to 100Mbit/s Bug was a regression first seen in the 5.15 Armbian kernel caused by a rewrite of speed setting for rk3308 in dwmc-rk.c that for some bizarre reason completely omitted the code needed to reprogram the MAC clock as appropriate for the selected Ethernet speed.
