The problem that I’m facing is that I’m not able to ping (send/receive data) using the interface swp1 (RJ45).
We tried to remove the flow control rx/tx using the ethtool using the following command before assigning an ip address to the interface and I was able to ping :
~# ethtool -A swp1 autoneg off rx off tx off
~# [ 128.775236] mscc_felix 0000:00:00.5 swp1: Link is Down
[ 131.557587] mscc_felix 0000:00:00.5 swp1: Link is Up - 1Gbps/Full - flow control off ping 192.168.3.222
PING 192.168.3.222 (192.168.3.222): 56 data bytes
64 bytes from 192.168.3.222: seq=0 ttl=128 time=0.861 ms
64 bytes from 192.168.3.222: seq=1 ttl=128 time=0.674 ms
Unfortunately, I lose the connection (ping) if I remove and replug the cable, if I try to test the interface from ethtool
~# ethtool -t swp1
The test result is FAIL
The test extra info:
1. Carrier 0
2. PHY dev is present 0
3. PHY internal loopback, enab 0
4. PHY internal loopback, UDP -110
5. PHY internal loopback, MTU -110
6. PHY internal loopback, TCP -110
7. PHY internal loopback, disa 0
This behavior is the same for linux kernel version 5.15 , 6.1.35 and 6.5.7 (we wanted to make sure that it was not a driver issue that is fixed in a newer version)
