DCA1000EVM: 使用DCA1000EVM从以太网端口获取数据格式不明确

Part Number: DCA1000EVM


DCA1000EVM Data Capture Card.pdf中5.2节关于Raw Mode Data描述中最大时1462 Bytes,

而在DCA1000EVM CLI Software Developer Guide2.5 FPGA节第79页关于Raw Mode描述中Data最大1456Bytes。我不知道哪个是对的,并且是否是因为版本更新而带来的差异?

并且在上图中,UDP Package (Max to 1472Bytes)最后只剩(1466Bytes),差出的6Bytes是因为什么呢
