* Dissector for Hilscher netANALYZER frames.
|
|
* Copyright 2008-2016, Hilscher GmbH, Holger Pfrommer hpfrommer[AT]hilscher.com
|

*
|
|
* Packet structure:
|
|
* +---------------------------+
|
|
* | Header |
|
|
* | (4 Octets) |
|
|
* +---------------------------+
|
|
* | Payload |
|
|
* . .
|
|
* . .
|
|
* . .
|
|
*
|
|
* Description:
|
|
* The header field contains a 32-bit value in little-endian byte order.
|
|
* The low-order 8 bits are a set of error flags for the packet:
|
|
* 0x00000001 - MII RX_ER
|
|
* 0x00000002 - alignment error
|
|
* 0x00000004 - FCS error
|
|
* 0x00000008 - frame too long
|
|
* 0x00000010 - SFD error
|
|
* 0x00000020 - frame shorter than 64 bytes
|
|
* 0x00000040 - preamble shorter than 7 bytes
|
|
* 0x00000080 - preamble longer than 7 bytes/li>
|
|
* The next bit, 0x00000100, is set if the packet arrived on the GPIO port rather tha the Ethernet port.
|
|
* The next bit, 0x00000200, is set if the packet was received in transparent capture mode.
|
|
* That should never be set for LINKTYPE_NETANALYZER and should always be set for LINKTYPE_NETANALYZER_TRANSPARENT.
|
|
* The next 4 bits, 0x00003C00, are a bitfield giving the version of the header field; version can be 1 or 2.
|
|
* The next 2 bits, 0x0000C000, are the capture port/GPIO number, from 0 to 3.
|
|
* The next 12 bits, 0x0FFF0000, are the frame length, in bytes.
|
|
* The topmost 4 bits, 0xF0000000, for version 2 header, these bits are the type of the following packet
|
|
* (0: Ethernet, 1: PROFIBUS, 2: buffer state entry, 3: timetick, 4..15: reserved).
|
|
* The payload is an Ethernet frame, beginning with the MAC header and ending with the FCS, for LINKTYPE_NETANALYZER,
|
|
* and an Ethernet frame, beginning with the preamble and ending with the FCS, for LINKTYPE_NETANALYZER_TRANSPARENT.
