DFSPacket p = createPacket(packetSize, chunksPerPacket,
streamer.getBytesCurBlock(),
streamer.getAndIncCurrentSeqno(), false);
int maxBytesToPacket = p.getMaxChunks() * bytesPerChecksum;
int toWrite = byteBuffer.remaining() > maxBytesToPacket ?
maxBytesToPacket: byteBuffer.remaining();
p.writeData(byteBuffer, toWrite);
streamer.incBytesCurBlock(toWrite);
packets.add(p);
