My interpretation of those bits is different, I'd say you had a Tx FIFO underflow.
Looking at the driver it doesn't seem to set the Tcr anywhere so you'll get the
default, try setting it to something larger, say store and forward. There's no
setting of the receive configuration either..
Of course, the datasheet is sketchy at best and I could be completely mistaken as
to what's going on.
