There are multiple differences compared to U-Boot does. I haven't yet been able to definitively determine the cause for regression. I'll debug more tomorrow. Preliminary testing shows that any link timer values > 0.84 ms will cause in-band autoneg to not complete with this combination. To be clear, does your board work with this patch?
Yes I tested it, I can provide you any logs you would find useful. Below is just a short log from interface bring up and simple iperf3 test: root@tru-:~# ip link set up swp0 [ 60.159618] mscc_felix 0000:00:00.5 swp0: configuring for inband/10g-qxgmii link mode [ 63.308354] mscc_felix 0000:00:00.5 swp0: Link is Up - 1Gbps/Full - flow control off root@tru-:~# ip addr add 192.168.10.2/24 dev swp0 root@tru-:~# iperf3 -s 192.168.10.2 ----------------------------------------------------------- Server listening on 5201 (test #1) ----------------------------------------------------------- Accepted connection from 192.168.10.1, port 44470 [ 5] local 192.168.10.2 port 5201 connected to 192.168.10.1 port 44484 [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 111 MBytes 933 Mbits/sec [ 5] 1.00-2.00 sec 111 MBytes 934 Mbits/sec [ 5] 2.00-3.00 sec 112 MBytes 935 Mbits/sec [ 5] 3.00-4.00 sec 111 MBytes 934 Mbits/sec [ 5] 4.00-5.00 sec 111 MBytes 934 Mbits/sec [ 5] 5.00-6.00 sec 111 MBytes 934 Mbits/sec [ 5] 6.00-7.00 sec 111 MBytes 934 Mbits/sec [ 5] 7.00-8.00 sec 111 MBytes 934 Mbits/sec [ 5] 8.00-9.00 sec 111 MBytes 934 Mbits/sec [ 5] 9.00-10.00 sec 111 MBytes 934 Mbits/sec [ 5] 10.00-10.24 sec 2.25 MBytes 77.7 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate [ 5] 0.00-10.24 sec 1.09 GBytes 914 Mbits/sec receiver Will also try to find out what could possibly go wrong.
