[PATCH] sundance: remove TxStartThresh and RxEarlyThresh
For patent issue need to remove TxStartThresh and RxEarlyThresh. This patent
is cut-through patent. If use this function, Tx will start to transmit after
few data be move in to Tx FIFO. We are not allow to use those function in
DFE530/DFE550/DFE580/DL10050/IP100/IP100A. It will decrease a little
performance.
