// Note on XmitBuffer: generally, 'lenleft' will start out as the number of data bytes,
// and 'nsent' will start as 0.  As more data is sent, nsent will move to the original lenleft,
// while lenleft will move to 0.
// Also note that malloc/free are used to allocate this structure, since
// data[] will be followed by (lenleft-1) more bytes, to house the data.
