No, sorry, my last mail was not clear about this. The failure was on a QCA8337 user port connected to a NAS, not on the IPQ5018 CPU link from the DAC investigation. With the same OpenWrt 6.18.52 diagnostic image and unchanged DAC settings, switching only that user PHY's read_status changed the MAC speed from an incorrect 1000 Mb/s to the actual 100 Mb/s and restored ping in both directions. > Reporting the correct downshift has nothing to do with that, as far as > i understand. Correctly reporting downshift i would put to net-next. If net-next is still your preference with that in mind, I will send v2 there. Thanks, Yongzhao Chen
