So for what it's worth I've tested this on a number of different ethernet=
 cables of various lengths, and a few different switches. All with the sa=
me results. If it's plugged into the dock then linux only negotiates as f=
ast as 100mbit, while plugging into the the X220 itself (not attached to =
the dock) or via a USB3 gigabit dongle plugged into the USB3 port on the =
dock, I can get up to gigabit.
