Both the programming manual and the Intel's library code say it's
bit 2. Must be a mistake in the old code. Unfortunately I think we
won't be able to check it on real hardware, the UDC on IXP4xx boards
isn't usually connected. Also, this bug wouldn't likely affect
operation (unless there is an overflow event, which would be
currently undetected).

I guess we as well very safely change it to 1 << 2.


For the IXP4xx part,
