[ltp] 100mbit only when docked?

[Jeffrey L. Taylor]

When plugged into the dock, you are not using the Ethernet chip in the
laptop.  You are using the chip in the dock.  Same for the sound and the
video.  On my T520, the chip is a ASIX Electronics Corp. AX88772A Fast
Ethernet.  lsusb only reports support for 10Mb and 100Mb Ethernet.  Fast
Ethernet seems to be 100Mb.  Other chips support Gigabit Ethernet.

HTH,

> I have an X220 running Debian Sid and one of those ultra mini 3 docks. I just noticed that e1000e can't negotiate anything beyond 100mbit when plugged in through the dock. If I plug it using the same cable/switch into the ethernet port on my laptop without the dock I can get 1000mbit without truoble.
