The RTL8157 chipset works with 2.18-1-1.

[nogcha234]

The RTL8157 chipset works with 2.18-1-1. 2.18-1.1 package shows the RTL8157 chipset in action.

I actually confirmed that data transfer at 5GbE speed is possible. However, I can't check the link speed connected to 5000Mbps (5GbE) in Synology's ethtool or Synology network information, and I can't modify the MTU.

This problem is unlikely to be fixed right away, but I'll leave it here for reference.

The product used is WisdPi WT-UT5.

Same here, the MTU cannot be set either via Synology tool or the shell The ifconfig returned: TNETLINK answers: Invalid argument The ip tool returned: RTNETLINK answers: Invalid argument

This is lack of Link Speed is also an issue for Active/Standby on bonding. The below eth2 is the wisdpi r8157-based adapter, connected to 10G switch. However, it seems the bonding driver still decides not to use this adapter even though the primary slave is set to it. After digging a while it seems like the bonding driver doesn't like the Unknown speed and duplex. From dmesg, the link speed is 0 Mbps for some reason.

@yunhao-jiang Many 10Gbps SFP modules do not negotiate the 5Gbps speed correctly, although they may function normally. You need to use an SFP module that supports the 5Gbps speed for testing. We will investigate this issue.

@yunhao-jiang Tested works. Speeds exceeding 5000Mb/s and bond supported.
