[6.10.0-RC1] Intel X550-T2 cannot auto negotiate 2.5Gbit link
LAN adapter: Intel X550-T2
Switch: TP-Link TL-SG108-M2
[8086:1563] 07:00.0 Ethernet controller: Intel Corporation Ethernet Controller 10G X550T (rev 01)
[8086:1563] 07:00.1 Ethernet controller: Intel Corporation Ethernet Controller 10G X550T (rev 01)
Asus XT8 access point can successfully negotiate 2.5Gbit link on the switch, but the Intel X550-T2 only negotiates 1Gbit, 2500baseT/Full and 5000baseT/Full are listed as supported but are not advertised:

Minor
Try with this:
/usr/sbin/ethtool -s eth0 speed 2500 duplex full
/usr/sbin/ethtool -s eth1 speed 2500 duplex full
/sbin/ifconfig eth0 down
/sbin/ifconfig eth1 down
/sbin/ifconfig eth0 up
/sbin/ifconfig eth1 up
Hopefully bringing the interfaces down and up will solve the issue 🤞
