Function decodeModbusTCP

layers/modbustcp.go:79–94

****************************************************************************** decodeModbusTCP analyses a byte slice and attempts to decode it as an ModbusTCP record of a TCP packet. If it succeeds, it loads p with information about the packet and returns nil. If it fails, it returns an error (non
