e1000e on Thinkpad x60: gigabit not available due to "SmartSpeed"

e1000e on Thinkpad x60: gigabit not available due to "SmartSpeed"

[Pavel Machek]

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

Check your cables?

Of course if it isn't the cable, then it could even be a broken pin in
the port.  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.

Ok, so it seems like broken pin in the port. I realized I had docking
station available for the machine, and when connecting using that
connector (not internal notebook one), I get gigabit speed.

Thanks and best regards,
