Hi! I have trouble getting 1000mbit out of my ethernet card. I tried direct connection between two PCs with different cables, and no luck. Today I tried connection to 1000mbit switch, and no luck, either. (Two cables, one was cat6, both short). My computer sees 1000mbit being advertised by the other side, but does not advertise 1000mbit, "Link Speed was downgraded by SmartSpeed". 4.8.0-rc4+ kernel. Does it work for other people? Card is: 02:00.0 Ethernet controller: Intel Corporation 82573L Gigabit Ethernet Controller root@duo:/data/l/linux# mii-tool -v eth1 SIOCGMIIREG on eth1 failed: Input/output error SIOCGMIIREG on eth1 failed: Input/output error eth1: negotiated 100baseTx-FD, link ok product info: Yukon-EC 88E1111 rev 0 basic mode: autonegotiation enabled basic status: autonegotiation complete, link ok capabilities: 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD advertising: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control link partner: 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD root@duo:/data/l/linux# [ 1330.622658] e1000e: eth1 NIC Link is Up 100 Mbps Full Duplex, Flow Control: None [ 1330.622840] e1000e 0000:02:00.0 eth1: Link Speed was downgraded by SmartSpeed [ 1330.622846] e1000e 0000:02:00.0 eth1: 10/100 speed: disabling TSO root@duo:/data/l/linux# Best regards, Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html

As far as I can tell, anything that causes one of the 3rd or 4th pairs of wires to not work will degrade to 100Mbit on just the first 2 pairs of wires and give that message. Some badly implemented switches can also cause it of course. -- Len Sorensen
