Well, Doug White asked for documentation. When it comes to the Gigabit
Ethernet, I believe the IEEE standards are about as authoritative as you
can get.

If you check the specs for some of the Intel Gigabit Ethernet cards,
e.g.

http://www.intel.com/network/connectivity/resources/doc_library/data_sheets/pro1000gt_da.pdf

you'll see that they refer to 100base-TX, but 1000base-T.

So I stand by my claim that 1000base-T is clearly more correct than
1000baseTX. It would be nice to get this fixed - however, it is a
minor point and I certainly believe that there are other tasks that
are more important.
