As with the output from snoop, we have to extract each of the blocks of data from the raw network packet information.
如果所需的大小大于现有的块，那么释放这个块，从另一个bucket分配一个新的块，把数据从原来的块转移到新的块中。
If the needed size happens to be greater than the existing block, the block is freed, a new block is allocated from a new bucket, and the data is moved from the old block to the new block.
