[SPARC64]: Assorted LDC bug cures.
1) LDC_MODE_RELIABLE is deprecated an unused by anything, plus
it and LDC_MODE_STREAM were mis-numbered.
2) read_stream() should try to read as much as possible into
the per-LDC stream buffer area, so do not trim the read_nonraw()
length by the caller's size parameter.
3) Send data ACKs when necessary in read_nonraw().
4) In read_nonraw() when we get a pure ACK, advance the RX head
unconditionally past it.
5) Provide the ACKID field in the ldcdgb() packet dump in read_nonraw().
This helps debugging stream mode LDC channel problems.
6) Decrease verbosity of rx_data_wait() so that it is more useful.
A debugging message each loop iteration is too much.
7) In process_data_ack() stop the loop checking when we hit lp->tx_tail
not lp->tx_head.
8) Set the seqid field properly in send_data_nack().
